The issue in this case is whether the evidence used against Robinette was obtained through a valid search. We find that the . search was invalid since it was the product of an unlawful seizure. We also use this case to establish a bright-line test, requiring police officers to inform motorists that their legal detention has concluded before the police officer may engage in any consensual interrogation.
In order to justify any investigative stop, a police officer “must be able to point to specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant that intrusion.” Terry v. Ohio (1968), 392 U.S, 1, 21, 88 S.Ct. 1868, 1880, 20 L.Ed.2d 889, 906. Absent any additional articulable facts arising after the stop is made, the police officer must tailor his detention of the driver to the original purpose of the stop. State v. Chatton (1984), 11 Ohio St.3d 59, 63, 11 OBR 250, 253, 463 N.E.2d 1237, 1240.
In Chatton, the police officer stopped the defendant’s car when he noticed it had no license plates. When he approached the car after it had pulled over, the *653officer saw a valid temporary tag in the car’s rear window. Despite the fact that the original question which gave rise to the stop had been resolved, the officer approached the driver and asked to see his driver’s license. A check of the license revealed that it was suspended, and the officer ordered the defendant out of his vehicle and placed him under arrest for driving with a suspended license. Upon searching the vehicle, the officer discovered a loaded revolver under the driver’s seat. The defendant was charged with carrying a concealed weapon.
This court ruled in Chatton that the evidence resulting from the search should have been suppressed. This court reasoned that the officer, upon seeing the valid temporary tag, no longer maintained a reasonable suspicion that the defendant’s vehicle was not properly licensed, and thus had no articulable reason to further detain the defendant to determine the validity of his driver’s license. As a result, any evidence seized upon a subsequent search of the vehicle was inadmissible under the Fourth Amendment to the United States Constitution.
In this case, Newsome certainly had cause to pull over Robinette for speeding. The question is when the validity of that stop ceased. Newsome testified that from the outset he never intended to ticket Robinette for speeding. When Newsome returned to Robinette’s car after checking Robinette’s license, every aspect of the speeding violation had been investigated and resolved. All New-some had to do was to issue his warning and return Robinette’s driver’s license.
Instead, for no reason related to the speeding violation, and based on no articulable facts, Newsome extended his detention of Robinette by ordering him out of the vehicle. Newsome retained Robinette’s driver’s license and told Robinette to stand in front of the cruiser. Newsome then returned to the cruiser and activated the video camera in order to record his questioning of Robinette regarding whether he was carrying any contraband in the vehicle.
When the motivation behind a police officer’s continued detention of a person stopped for a traffic violation is not related to the purpose of the original, constitutional stop, and when that continued detention is not based on any articulable facts giving rise to a suspicion of some separate illegal activity justifying an extension of the detention, the continued detention constitutes an illegal seizure. Chatton, supra.
The entire chain of events, starting when Newsome had Robinette exit the car and stand within the field of the video camera, was related to the questioning of Robinette about carrying contraband. Newsome asked Robinette to step out of his car for the sole purpose of conducting a line of questioning that was not related to the initial speeding stop and that was not based on any specific or articulable facts that would provide probable cause for the extension of the scope of the seizure of Robinette, his passenger and his car. Therefore the detention of Robinette ceased being legal when Newsome asked him to leave his vehicle.
*654However, this case contains a feature not discussed in Chatton: Robinette consented to the search of his vehicle during the illegal seizure. Because Robinette’s consent was obtained during an illegal detention, his consent is invalid unless the state proves that the consent was not the product of the illegal detention but the result of an independent act of free will. Florida v. Royer (1983), 460 U.S. 491, 501, 103 S.Ct. 1319, 1326, 75 L.Ed.2d 229, 238. The burden is on the state to prove that the consent to search was voluntarily given. Id. at 497, 103 S.Ct. at 1324, 75 L.Ed.2d at 236. The factors used in consideration of whether the consent is sufficiently removed from the taint of the illegal seizure include the length of time between the illegal seizure and the subsequent search, the presence of intervening circumstances, and the purpose and flagrancy of the circumstances. United States v. Richardson (C.A.6, 1991), 949 F.2d 851, 858.
In this case there was no time lapse between the illegal detention and the request to search, nor were there any circumstances that might have served to break or weaken the connection between one and the other. The sole purpose of the continued detention was to illegally broaden the scope of the original detention. Robinette’s consent clearly was the result of his illegal detention, and was not the result of an act of will on his part. Given the circumstances, Robinette felt that he had no choice but to comply.
This case demonstrates the need for this court to draw a bright line between the conclusion of a valid seizure and the beginning of a consensual exchange. A person has been seized for the purposes of the Fourth Amendment when a law enforcement officer, by means of physical force or show of authority, has in some way restrained his liberty such that a reasonable person would not feel free to walk away. United States v. Mendenhall (1980), 446 U.S. 544, 553-554, 100 S.Ct. 1870, 1877, 64 L.Ed.2d 497, 509.
The transition between detention and a consensual exchange can be so seamless that the untrained eye may not notice that it has occurred. The undetectability of that transition may be used by police officers to coerce citizens into answering questions that they need not answer, or to allow a search of a vehicle that they are not legally obligated to allow.
The present case offers an example of the blurring between a legal detention and an attempt at consensual interaction. Even assuming that Newsome’s detention of Robinette was legal through the time when Newsome handed back Robinette's driver's license, Newsome then said, "One question before you get gone: are you carrying any illegal contraband in your car?” (Emphasis added.) Newsome tells Robinette that before he leaves Newsome wants to know whether Robinette is carrying any contraband. Newsome does not ask if he may ask a question, he simply asks it, implying that Robinette must respond before he may *655leave. The interrogation then continues. Robinette is never told that he is free to go or that he may answer the question at his option.
Most people believe that they are validly in a police officer’s custody as long as the officer continues to interrogate them. The police officer retains the upper hand and the accouterments of authority. That the officer lacks legal license to continue to detain them is unknown to most citizens, and a reasonable person would not feel free to walk away as the officer continues to address him.
We are aware that consensual encounters between police and citizens are an important, and constitutional, investigative tool. Florida v. Bostick (1991), 501 U.S. 429, 111 S.Ct. 2382, 115 L.Ed.2d 389. However, citizens who have not been detained immediately prior to being encountered and questioned by police are more apt to realize that they need not respond to a police officer’s questions. A “consensual encounter” immediately following a detention is likely to be imbued with the authoritative aura of the detention. Without a clear break from the detention, the succeeding encounter is not consensual at all.
Therefore, we are convinced that the right, guaranteed by the federal and Ohio Constitutions, to be secure in one’s person and property requires that citizens stopped for traffic offenses be clearly informed by the detaining officer when they are free to go after a valid detention, before an officer attempts to engage in a consensual interrogation. Any attempt at consensual interrogation must be preceded by the phrase “At this time you legally are free to go” or by words of similar import.
While the legality of consensual encounters between police and citizens should be preserved, we do not believe that this legality should be used by police officers to turn a routine traffic stop into a fishing expedition for unrelated criminal activity. The Fourth Amendment to the federal Constitution and Section 14, Article I of the Ohio Constitution exist to protect citizens against such an unreasonable interference with their liberty.
Accordingly, the judgment of the court of appeals is affirmed.
Judgment affirmed.
