The Government appeals from an Order of the United States District Court for the Southern District of New York (Naomi Reice Buchwald, Judge) granting defendant’s motion to suppress evidence seized when a police officer, after lawfully entering the defendant’s home to execute several arrest warrants and lawfully engaging in a protective sweep of the premises, conducted a warrantless search of a suitcase inside defendant’s home. The District Court, in a ruling from the bench relying on Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987), held that the search violated defendant’s reasonable expectation of privacy in his home.
We vacate the suppression order and remand the cause to the District Court for consideration of the issue of defendant’s expectation of privacy in the suitcase.
I. BACKGROUND
In February 2000, defendant-appellant Samad Haqq lived in a two-bedroom apartment in New York City rented by his fiancée, Francine Harris. It is undisputed that at least four people lived in that apartment: Haqq, Francine Harris, Cedric Harris (Francine Harris’s six-year-old son), and Reginald Peavy, a friend of Francine Harris’s who paid her $75 per week and slept in one of the bedrooms. According to Haqq, another unrelated man, Samuel Myers, also lived in the apartment and slept in the living room.
On the morning of February 9, 2000, New York City police officers, including Detective Ralph Hanna, went to the Harris apartment to arrest Haqq, who was the subject of several outstanding arrest warrants. When they arrived at Harris’s apartment, the officers knocked on the door and identified themselves. For five to ten minutes, there was no response; thereafter, Myers opened the door. The officers immediately handcuffed both Myers and Haqq. Leaving Haqq and Myers under guard in the living room, Hanna and another officer conducted a protective sweep of the apartment to ensure that no one else was on the premises.
As part of the protective sweep, Hanna entered the back bedroom of the apartment, where he observed a black nylon suitcase on top of the bed in the center of the room. Hanna searched the suitcase and discovered three handguns.
After seizing the guns, the officers took Haqq to a nearby police station, where Haqq signed a written statement in which he admitted that he had bought the guns *46to repay a debt to a drug dealer who wanted some “throwaway” weapons. The police then obtained Haqq’s consent to a further search of the apartment, where they found two additional handguns and ammunition.
Haqq was subsequently charged in a two-count indictment with possessing firearms after having been convicted of a felony, in violation of 18 U.S.C. § 922(g)(1),1 and possessing a firearm with an obliterated serial number, in violation of 18 U.S.C. § 922(k).2 Haqq moved to suppress the firearms seized from his apartment and his confession, contending that the initial search of the suitcase was unlawful and that the confession and subsequent search were fruits of the proverbial “poisonous tree.” The Government conceded that, if the initial search of the suitcase were unlawful, then the confession and subsequent search would be subject to suppression, but it argued that the initial search had not violated Haqq’s Fourth Amendment rights for two independent reasons: because the guns were in plain view, and because Haqq had no reasonable expectation of privacy in the suitcase.
The District Court held evidentiary hearings on the suppression motion on September 19, November 6, and November 21, 2000. At those hearings, Hanna testified that, when he entered the back bedroom, he saw the outline of a handgun through the suitcase, and that he touched the outline, felt a gun, and then opened the pouch to discover three handguns. He also testified that the main compartment of the suitcase contained shoes, which filled “most” of the suitcase.
Despite being given several opportunities in open court to recreate the condition in which the suitcase was found, the Government was unable to repack the suitcase in such a way as to make the outline of a gun visible in the way described by Hanna, except by overstuffing the suitcase with numerous boxes. The District Court found the demonstration involving boxes unconvincing, noting that “no one claims [boxes] were ever actually in the suitcase[, and, w]hen packed with any number of shoes, the protrusion from the suitcase is not recognizable as a gun.” Hr’g Tr. dated Dec. 18, 2000, at 10.
With respect to Haqq’s expectation of privacy in the suitcase, the testimony at the hearing revealed that the suitcase belonged to Peavy, not Haqq, and that the bedroom in which Hanna found the suitcase was the one in which Peavy slept. The room was also occasionally slept in by Cedric Harris, and Francine Harris would sometimes care for Cedric in the room.
None of the contents of the suitcase at the time it was searched belonged to Peavy; the shoes belonged to Haqq, *47Myers, and Myers’s sister. Haqq had used the suitcase during a trip to the Carolinas with Myers, and Myers had placed it in Peavy’s room upon their return earlier on the very morning of the execution of the arrest warrants by the police, February 9, 2000.
Haqq and Peavy gave conflicting testimony regarding whether Haqq had Peavy’s permission to use the suitcase. According to Haqq, Peavy had given him permission to use the suitcase for the Carolina trip, and, in any event, they had an understanding that permitted each of them to use the other’s belongings. Peavy denied ever giving Haqq permission to use the suitcase and also denied the existence of any understanding with Haqq regarding use of belongings.
The District Court granted the motion to suppress. Relying on Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987), it held that Haqq’s reasonable expectation of privacy in his home was “sufficient to permit him to object to the seizures of objects which were not, in fact, in plain view.” Hr’g Tr. dated Dec. 18, 2000, at 6. Because it based its decision on Haqq’s reasonable expectation of privacy in his home, the District Court concluded that it was unnecessary to resolve the factual dispute over Haqq’s property interest in the suitcase itself:
Even assuming arguendo that the defendant lacked a specific property interest in the container within his home preventing the object inside from being viewed, he had a reasonable expectation of privacy to object to an allegedly unlawful search of his home.
Id. at 6-7. The District Court then found, as a factual matter, that the guns had not been in plain view.
On appeal, the Government challenges only the finding that Haqq’s reasonable expectation of privacy in his home was violated by the search of the suitcase. It argues that Haqq’s Fourth Amendment rights were not violated unless he had a reasonable expectation of privacy in the suitcase, and that he could have no such expectation because he did not own it and, even if he had permission to borrow it, he had returned it to Peavy by putting it on Peavy’s bed in the room that Peavy was renting.
II. DISCUSSION
It has been clear for a generation that “Fourth Amendment rights are personal rights ... [that] may not be vicariously asserted.” Rakas v. Illinois, 439 U.S. 128, 133-34, 99 S.Ct. 421, 58 L.Ed.2d 387 (1978). Accordingly, a defendant’s Fourth Amendment rights are violated “only when the challenged conduct invaded his legitimate expectation of privacy rather than that of a third party.” United States v. Payner, 447 U.S. 727, 731, 100 S.Ct. 2439, 65 L.Ed.2d 468 (1980) (emphasis in original). The cornerstone of the modern law of searches is the principle that, to mount a successful Fourth Amendment challenge, “a defendant must demonstrate that he personally has an expectation of privacy in the place searched.” Minnesota v. Carter, 525 U.S. 83, 88, 119 S.Ct. 469, 142 L.Ed.2d 373 (1998) (emphasis added); see also United States v. Fields, 113 F.3d 313, 322 (2d Cir.1997) (“The ultimate focus of Fourth Amendment analysis remains whether the defendant had a reasonable expectation of privacy in the place searched.”). A defendant must also show “that his expectation [of privacy] is reasonable, ie. one that has a ‘source outside the Fourth Amendment, either by reference to concepts of real or personal property law or to understandings that are recognized and permitted by society.’” Carter, 525 U.S. at 88, 119 S.Ct. 469 (quoting Rakas, 439 U.S. at 143 n. 12, 99 S.Ct. 421).
*48In this case, the District Court held that search of the suitcase violated Haqq’s reasonable expectation of privacy in his home. Thus, the District Court, in essence, treated the search of the suitcase in Haqq’s home as part of a search o/his home. The District Court found support for its conclusion in Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987). We conclude, however, that the District Court misapprehended the holding of Hicks.
The facts of Hicks are as follows: After a bullet was fired through the floor of the defendant’s apartment into the apartment below, police officers entered defendant’s apartment (without a warrant) to search for the shooter, for other victims, and for weapons. 480 U.S. at 323, 107 S.Ct. 1149. One of the officers noticed that the apartment contained expensive stereo equipment, which “seemed out of place.” Id. Suspecting the equipment was stolen, he moved some of the stereo components so that he could observe and record their serial numbers. Id. The stereo equipment was, in fact, stolen in an armed robbery, and the defendant was subsequently indicted for the robbery. Id. at 323-24, 107 S.Ct. 1149. After the defendant successfully moved in State court to suppress the stereo equipment on the grounds that the officer’s actions violated his rights under the Fourth Amendment to the United States Constitution,3 the State appealed to the United States Supreme Court, contending, inter alia, that the officer’s actions with respect to the stereo equipment constituted neither a search nor a seizure within the meaning of the Amendment. Id. at 324,107 S.Ct. 1149.
In the portion of Hicks most relevant to the issues presented in this case, the Supreme Court rejected that argument. In the Court’s words,
Officer Nelson’s moving of the equipment, however, did constitute a “search” separate and apart from the search for the shooter, victims, and weapons that was the lawful objective of his entry into the apartment. Merely inspecting those parts of the turntable that came into view during the latter search would not have constituted an independent search, because it would have produced no additional invasion of respondent’s privacy interest. See Illinois v. Andreas, 463 U.S. 765, 771, 103 S.Ct. 3319, 77 L.Ed.2d 1003 (1983). But taking action, unrelated to the objectives of the authorized intrusion, which exposed to view concealed portions of the apartment or its contents, did produce a new invasion of respondent’s privacy unjustified by the exigent circumstance that validated the entry.... It matters not that the search uncovered nothing of any great personal value to respondent — serial numbers rather than (what might conceivably have been hidden behind or under the equipment) letters or photographs. A search is a search, even if it happens to disclose nothing but the bottom of a turntable.
Id. at 324-25, 107 S.Ct. 1149 (emphasis added). Because the search of the turntable had not been supported by probable cause, the Court held that the search had violated the defendant’s Fourth Amendment rights. Id. at 326-29, 107 S.Ct. 1149.
All of the concurring and dissenting opinions in Hicks reflect an understanding *49that the search at issue in that case was a search of the stereo equipment — and not of Hicks’s home. See Hicks, 480 U.S. at 330, 107 S.Ct. 1149 (White, J., concurring) (“The police officers conducted a search of respondent’s stereo equipment absent probable cause that the equipment was stolen.” (emphasis added)); id. at 332, 107 S.Ct. 1149 (Powell, J., dissenting) (“The Court holds that there was an unlawful search of the turntable.” (emphasis added)); id. at 333, 107 S.Ct. 1149 (O’Connor, J., dissenting) (“The Court asks whether the police must have probable cause before ... conducting a full-blown search of [an] object [in plain view], and concludes that they must.” (emphasis added)). In a few subsequent decisions, the Supreme Court has similarly described Hicks as a case about the search or seizure of “an object,” rather than about an impermissibly broad search of a home. See, e.g., Minnesota v. Dickerson, 508 U.S. 366, 375, 113 S.Ct. 2130, 124 L.Ed.2d 334 (1993); Soldal v. Cook County, 506 U.S. 56, 66, 113 S.Ct. 538, 121 L.Ed.2d 450 (1992). But cf. Kyllo v. United States, 533 U.S. 27,-, 121 S.Ct. 2038, 2045, 150 L.Ed.2d 94 (2001) (“[I]n Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987), the only thing detected by a physical search that went beyond what officers lawfully present could observe in ‘plain view' was the registration number of a phonograph turntable. [This was an] intimate detail[ ] because [it was a] detail[] of the home_”). As a result, we read Hicks to hold that the search of the stereo equipment — and not the search of the defendant’s home (which was prompted and otherwise justified by exigent circumstances) — violated the defendant’s Fourth Amendment rights.
In the instant case, however, the District Court read Hicks differently. In the District Court’s view, Hicks supports the broad proposition that a defendant’s “reasonable expectation of privacy in his home [is] sufficient to permit him to object to the seizure of objects [within the home] which [are] not in fact in plain view.”4 Hr’g Tr. dated Dec. 18, 2000, at 6. The District Court’s interpretation of Hicks is apparently based on the assumption that because the stereo equipment in that case was stolen, the defendant could not have had a reasonable expectation of privacy in it. In the District Court’s view, Hicks teaches that “even where property is in fact stolen, a defendant may object to a constitutionally impermissible search within his home despite the absence of an ownership or possessory interest in the item itself.” Id. (emphasis added). We disagree.
If Hicks were read to mean, in the context of a single dwelling shared by several unrelated individuals, that each auto*50matically has a reasonable expectation of privacy in the whole dwelling, so that each person’s reasonable expectation of privacy is violated when there is an impermissible search of an object in the dwelling (but not the dwelling itself), regardless of who owns the object or possesses it, or in whose room or space it is located, then Hicks would have created an exception, sub si-lentio, to the rule first applied twenty years earlier in Katz v. United States, 389 U.S. 347, 353, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967), that “capacity to claim the protection of the Fourth Amendment depends ... upon whether the person who claims the protection of the Amendment has a legitimate expectation of privacy in the invaded place.” Rakas, 439 U.S. at 143, 99 S.Ct. 421 (interpreting Katz). But neither Rakas nor any other case applying this rule has suggested that it might not apply to a search of an object in the home. To the contrary, when considering the legality of a search of an object within a home, courts have properly focused on the defendant’s expectation of privacy in the object apart from his expectation of privacy in the home. See, e.g., United States v. Gonzalez, 940 F.2d 1413, 1420 n. 7 (11th Cir.1991) (homeowner lacked a reasonable expectation of privacy in a briefcase in the possession of a casual visitor to his home); United States v. Garcia-Rosa, 876 F.2d 209, 219-20 (1st Cir.1989) (homeowner lacked a reasonable expectation of privacy in a box located in his wife’s dresser where he claimed no interest in the box or its contents); see also 3 Wayne R. LaFave et AL., CRIMINAL PROCEDURE § 9.1(b) n. 44 (1999) (“A person in possession of premises has standing with regard to a search of those premises and also a seizure of objects therein, and thus may have suppressed the fruits of either type of intrusion if found illegal, but does not also have standing as to the search of a container belonging to another in the premises.” (emphasis in original)). Similarly, courts have held that one who shares his home with another does not have a reasonable expectation of privacy in those areas of the home used exclusively by his roommate. See, e.g., Lenz v. Winburn, 51 F.3d 1540, 1549-50 (11th Cir.1995) (grandparents lacked reasonable expectation of privacy in closet in their home used exclusively by granddaughter); People v. Fleming, 36 Ill. App.3d 612, 345 N.E.2d 10, 14-15 (1975) (where defendant and his brother shared an apartment and brother kept his bedroom locked and kept key in his possession, defendant had no reasonable expectation of'privacy in the brother’s bedroom).
We conclude that Hicks was not a departure from the Supreme Court’s earlier Fourth Amendment jurisprudence. Accordingly, because the Supreme Court in Hicks held that the search of the stereo equipment was unlawful, it necessarily also found, contrary to the District Court’s assumption, that the defendant had a legitimate expectation of privacy in that equipment, despite its having been stolen. See Rakas, 439 U.S. at 140, 99 S.Ct. 421 (holding that the question of whether a defendant’s legitimate expectation of privacy was violated is part and parcel of a Fourth Amendment inquiry).
Such a conclusion is not as anomalous as suggested by the District Court. Although a thief certainly has no “ownership” interest in a stolen item, the law recognizes his “possessory” interest: “the well-settled common-law rule [is] that a thief in possession of stolen goods has an ownership interest superior to the world at large, save one with a better claim to the property.” See People v. Wilson, 93 N.Y.2d 222, 226 n. * 689 N.Y.S.2d 419, 422 n. *, 711 N.E.2d 633, 635 n. * (1999); see also Virgin Islands v. Edwards, 903 F.2d 267, 273 (3d Cir.1990) (“It has long been a principle of common law that one in pos*51session of property has the right to keep it against all but those with a better title.”); Anderson v. Gouldberg, 51 Minn. 294, 53 N.W. 636, 636 (1892) (holding that a thief may maintain a replevin action against a third party that deprived him of the stolen goods). While this possessory interest is insufficient, standing alone, to create a reasonable expectation of privacy in a stolen car in a driveway or on a commercial property, see United States v. Tropiano, 50 F.3d 157,161 (2d Cir.1995), when stolen property is kept inside a home it may not be searched without a warrant absent probable cause. See Hicks, 480 U.S. at 326-29,107 S.Ct. 1149; see also id. at 324-25, 107 S.Ct. 1149 (referring to Hicks’s “possessory interest” in the stolen stereo equipment); cf. Kyllo v. United States, 533 U.S. 27,-, 121 S.Ct. 2038, 2045, 150 L.Ed.2d 94 (2001) (“[I]n Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987), the only thing detected by a physical search that went beyond what officers lawfully present could observe in ‘plain view’ was the registration number of a [stolen] phonograph turntable. [This was an] intimate detail[ ] because [it was a] detail[ ] of the home.... ”).
It does not necessarily follow from the finding of a legitimate expectation of privacy in the stereo equipment in Hicks, however, that the defendant here had a legitimate expectation of privacy in the suitcase. In Hicks, there was no question about who had custody and control of the stereo equipment — Hicks was apparently the sole resident of the apartment in which the equipment was found, and the apartment was unoccupied when police entered. See State v. Hicks, 146 Ariz. 533, 707 P.2d 331, 332 (1985). Thus, the Supreme Court’s holding that the defendant in Hicks had a reasonable expectation of privacy in the stereo equipment reflects a conclusion that exclusive custody and control of an item within one’s home is sufficient to establish a reasonable expectation of privacy in that item. See Hicks, 480 U.S. at 324-25, 107 S.Ct. 1149 (holding that the movement of the stereo equipment “did not ‘meaningfully interfere’ with respondent’s possessory interest in ... the equipment,” but “did produce a new invasion of respondent’s privacy ” (emphasis added)). Here, in contrast, the Government contends that Haqq relinquished custody and control of Peavy’s suitcase when he returned it to Peavy’s room following the trip to the Car-olinas.
Resolution of this issue — which the District Court elided — as well as any other matter bearing on the determination of whether Haqq had a reasonable expectation of privacy in the suitcase (such as those discussed by Judge Meskill, post, at [443-45]), should be made, in the first instance, by the District Court. See United States v. Ali, 68 F.3d 1468, 1473 (2d Cir.1995). Nothing in this opinion should be read to suggest a view as to whether any expectation of privacy in the suitcase on the part of Haqq was reasonable.
III. Conclusion
In sum, we hold that the District Court erred in holding Haqq’s Fourth Amendment rights were violated by a police officer’s search of a suitcase in his home following the officer’s lawful entry into the home and into the bedroom where the suitcase was located without finding that the defendant had a reasonable expectation of privacy in the suitcase. Accordingly, we vacate the December 18, 2000, Order of the District Court granting Haqq’s motion to suppress, and remand the cause for further proceedings consistent with this opinion, including consideration of whether Haqq had a reasonable expectation of privacy in the suitcase.
. Title 18, section 922(g) of the United States Code provides, in relevant part:
It shall be unlawful for any person—
(1) who has been convicted in any court of, a crime punishable by imprisonment for a term exceeding one year;
to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
. Title 18, section 922(k) of the United States Code provides:
It shall be unlawful for any person knowingly to transport, ship, or receive, in interstate or foreign commerce, any firearm which has had the importer’s or manufacturer's serial number removed, obliterated, or altered or to possess or receive any firearm which has had the importer’s or manufacturer’s serial number removed, obliterated, or altered and has, at any time, been shipped or transported in interstate or foreign commerce.
. "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” U.S. Const Amend. IV
. According to the transcript of the hearing, the District Court purportedly referred to "an allegedly unlawful search of [Haqq's] home,” Hr'g Tr. dated Dec. 18, 2000, at 7 (emphasis added). But the logic of the opinion suggests that the reference should have been to "an allegedly unlawful search” in Haqq's home. Nothing in the record suggests that the search of the home was unlawful; other than Hanna's search of the suitcase, the only search of the home or any of its contents was a protective sweep for other persons or weapons, a search that Haqq conceded at the hearing was justified under the circumstances. The search of the suitcase was not part of an unjustified warrantless search of a home or even of numerous containers within a home. Cf. Alderman v. United States, 394 U.S. 165, 176-77, 89 S.Ct. 961, 22 L.Ed.2d 176 (1969) ("If the police make an unwarranted search of a house and seize tangible property belonging to third parties ... the homeowner may object to its use against him, not because he had any interest in the seized items as 'effects' protected by the Fourth Amendment, but because they were the fruits of an unauthorized search of his house, which is itself expressly protected by the Fourth Amendment.” (emphasis added)) (pre-Katz opinion).
