Ordered that the judgment is affirmed.
The Supreme Court properly credited the testimony of the trained police officer who stated that as he drove up behind the defendant in a location known to have been the site of narcotics sales, he saw the defendant give another man, in exchange for money, an envelope containing a white powdery substance (see, People v. Ellis, 198 A.D.2d 90, 91). In light of this testimony, the Supreme Court properly determined that there was probable cause to arrest the defendant (see, People v. McRay, 51 N.Y.2d 594, 604-605; see also, People v. Jeffrey, 207 A.D.2d 413; People v. Steinmetz, 195 A.D.2d 487). Accordingly, the drugs seized from the defendant were admissible and that branch of his motion which was to suppress physical evidence was properly denied. Balletta, J.P., Rosenblatt, Ritter and Pizzuto, JJ., concur.
