Ordered that the judgment is affirmed.
The information supplied to the police officers in a face-to-face meeting with an unidentified informant at the crime scene, together with the officers' subsequent observations, provided the police with a reasonable suspicion that the defendant had committed a crime involving a weapon (see, People v. Thorne, 184 A.D.2d 797; People v. DeJesus, 169 A.D.2d 521; People v. Castro, 115 A.D.2d 433, affd 68 N.Y.2d 850; People v Bero, 139 A.D.2d 581, 582). The reasonable suspicion justified not only the stop of the defendant but the frisk. "Since the lawful frisk produced a gun providing probable cause for the defendant's arrest" (People v. Thorne, supra, at 798), the court properly denied suppression. Mangano, P.J., O'Brien, Pizzuto and Santucci, JJ., concur.
