Ordered that the judgment is affirmed.
At the Mapp/Dunaway hearing, the police officer testified that he observed the defendant while conducting surveillance in an area which had a high incidence of narcotics trafficking. From his observation post, he saw the defendant exchange plastic packets, that he believed contained heroin, for currency. This testimony, when combined with the officer's experience and training, established probable cause for the defendant's arrest and the search incident thereto (see, People v. McRay, 51 N.Y.2d 594, 603-604). Accordingly, the Supreme Court properly denied suppression of the physical evidence.
The defendant failed to object or take exception to the court's charge or recharge to the jury and therefore, his claims of error with respect thereto are unpreserved for appellate review (see, CPL 470.05; People v. Ford, 66 N.Y.2d 428, 441).
Finally, we find no basis to reduce the defendant's sentence (see, People v. Suitte, 90 A.D.2d 80, 86). Mangano, P.J., Lawrence, Kunzeman and Kooper, JJ., concur.
