Appeal by defendant from a judgment of the County Court, Nassau County, rendered November 30, 1977, convicting him of criminal sale of a controlled substance in the third degree, upon a jury verdict, and imposing sentence. Judgment affirmed. Although the trial court erred in ruling that the facts underlying a pending indictment could be used against the defendant for purposes of attacking his credibility, under the circumstances presented here, we find the error to have been harmless (see People v. Mohammed, 63 A.D.2d 655; People v. Crimmins, 36 N.Y.2d 230). Lazer, J.P., Rabin, Gulotta and Cohalan, JJ., concur.
