Appeal by the defendant from a judgment of the Supreme Court, Queens County (Holder, J.), rendered August 19, 2010, convicting him of criminal sale of a controlled substance in the third degree (seven counts), upon a jury verdict, and imposing sentence.
Ordered that the judgment is affirmed.
The defendant’s contentions regarding the Supreme Court’s closure of the courtroom during the testimony of two undercover police detectives are unpreserved for appellate review (see CPL 470.05 [2]; People v James, 47 AD3d 947, 948 [2008]; People v Latta, 222 AD2d 303, 303-304 [1995]).

The defendant’s contention, also raised in his pro se supplemental brief, that the prosecutor presented perjured testimony, is likewise unpreserved for appellate review and, in any event, without merit (see People v Garcia, 57 AD3d 918, 919 [2008]).
