Ordered that the judgment is affirmed.
We have examined the record and find that the defendant, with the effective assistance of counsel, knowingly and voluntarily entered a plea of guilty. Moreover, the defendant, by his plea of guilty, forfeited his right to challenge the geographic jurisdiction of Nassau County to prosecute the instant offense (see, People v. Ianniello, 156 A.D.2d 469; People v. Hinestrosa, 121 A.D.2d 469; People v. Pirone, 108 A.D.2d 829; People v. Spears, 106 A.D.2d 417, 418).
The issues raised in the defendant's posttrial motion pursuant to CPL 440.10 are not properly before this Court as he failed to seek leave to appeal from the order denying the motion (see, People v. Green, 153 A.D.2d 644). Mangano, P.J., O'Brien, Ritter and Pizzuto, JJ., concur.
