OPINION OF THE COURT
On this appeal, defendant challenges, inter alia, the denial, after a hearing, of his motion to suppress certain physical evidence (i.e., $3,700 in marked bills) recovered during a search of his person incident to a warrantless — and it is argued, unlawful — arrest.
When the officers entered, there were four people in the store, including defendant. All were in the nonpublic area behind the counter, and one of them (but not the defendant) was in the back room. At the sight of the officers, the other three fled into the back room. Some of the officers then went behind the counter in an effort to apprehend the fleeing men, while others went around to the outside rear of the store to block any escape. Eventually, the officers were able to gain entrance to the back room where they apprehended the four individuals and brought them to the front of the store. After frisking them for weapons, the four were detained in the front of the store while the officers conducted a search of the premises pursuant to the search
The hearing court denied the motion to suppress, concluding, inter alia, that the police officers who had knowledge of the drug transaction which had transpired on the premises viewed the flight of the four individuals more seriously than one might view a person simply leaving a room under ordinary circumstances, particularly when coupled with the fact that they had announced their purpose and authority and had identified themselves by displaying their shields. The hearing court found that these facts, taken together with the contraband discovered in the back room, were sufficient to constitute probable cause to arrest. We affirm.
The validity of the search of defendant’s person is dependent upon whether there was probable cause to arrest him. Looking at all the facts here present, we find that there was probable cause for the warrantless arrest of defendant. In viewing the facts, it must be recognized that the existence of probable cause to arrest requires not “evidence sufficient to warrant a conviction * * * but merely information which would lead a reasonable person who possesses the same expertise as the [arresting] officer to conclude, under the circumstances, that a crime is being or was committed” (People v McRay, 51 NY2d 594, 602; People v Valentine, 17 NY2d 128). In the case at bar, the police knew that the premises were being used for drug trafficking and they knew that Bennett had gone into the store just prior to the raid for purposes of a drug transaction and thus could anticipate that the other participant or participants in the transaction were in the premises. At the time they entered the store defendant was in the nonpublic area of the store — as were the other three individuals — thus diminishing any probability that he was simply an ordinary customer. It is clear that ordinarily an individual’s
The instant case is distinguishable from those in which an individual merely happens to be on the scene or arrives on the scene during the execution of a search warrant for a premises which police suspect is connected with narcotics or other criminal activity (see, e.g., Ybarra v Illinois, 444 US 85, supra; People v Costales, 39 NY2d 973, supra; People v Nieves, 36 NY2d 396, supra). Here, defendant, who was at the scene of a drug transaction, did not play the role of an unaware innocent bystander; rather, he fled and successfully concealed, if only momentarily, himself and his activities from the police.
Moreover, even if probable cause to arrest did not exist at the time defendant was initially detained, it cannot be
The concept of probable cause, as its very name implies, deals with probabilities. The rules for its application are not technical but rather concern the “factual and practical considerations of everyday life on which reasonable and prudent men * * * act” (Brinegar v United States, 338 US 160, 175). In this case, those considerations and probabilities supported a reasonable conclusion by the police that defendant was involved in drug transactions on the premises. Thus, there was probable cause to make the arrest and the physical evidence was lawfully seized pursuant to that arrest.
