ORDERED that the judgment is affirmed.

Contrary to the defendant's contention, the Supreme Court properly denied his applications for new assigned counsel based upon an alleged conflict of interest and inadequate communication with his assigned counsel (see, People v. Sides, 75 N.Y.2d 822; People v. Arroyave, 49 N.Y.2d 264; People v. Estwick, 266 A.D.2d 123, 124). Whether to allow a defendant to substitute counsel is largely within the discretion of the Trial Judge (see, People v. Tineo, 64 N.Y.2d 531; People v. Arroyave, supra; People v. Chambers, 279 A.D.2d 353). The defendant must show good cause for the substitution, and the application must not be made merely as a dilatory tactic (see, People v. Arroyave, supra). The defendant's complaints about his assigned counsel consisted of conclusory allegations which were insufficient to show good cause, and his actions were merely a dilatory tactic (see, People v. Tineo, supra; People v. Chambers, supra).

The defendant was removed from the courtroom after a series of disruptive acts. After being removed, the defendant indicated through his counsel that he would continue the disruptive behavior if he returned to the courtroom. Under these circumstances, the Supreme Court providently exercised its discretion in removing the defendant from the courtroom (see, CPL 260.20; People v. Byrnes, 33 N.Y.2d 343; People v. Sherrod, 270 A.D.2d 366; People v. Phillips, 265 A.D.2d 237).

The defendant's contention that the evidence was legally insufficient to establish his guilt is unpreserved for appellate review (see, CPL 470.05; People v. Gray, 86 N.Y.2d 10; People v. Rivera, 275 A.D.2d 802; People v. White, 192 A.D.2d 736). In any event, viewing the evidence in the light most favorable to the prosecution (see, People v. Contes, 60 N.Y.2d 620), we find that it was legally sufficient to establish the defendant's guilt beyond a reasonable doubt (see, People v. Bracey, 41 N.Y.2d 296; People v. Rivera, supra; People v. Peralta, 261 A.D.2d 101; People v. Durden, 219 A.D.2d 605; cf., Matter of Marcel F., 233 A.D.2d 442). Moreover, upon the exercise of our factual review power, we are satisfied that the verdict of guilt was not against the weight of the evidence (see, CPL 470.15).

The Supreme Court should not have admitted a composite sketch of the suspect into evidence. Generally, a composite sketch is not admissible on the prosecution's direct case because of the "potential suggestiveness of having a police artist interpret and possibly influence the perceptions of the witness" (People v. Ross, 186 A.D.2d 1006), and it cannot be introduced to allow a witness to testify to an extrajudicial identification of the defendant (see, People v. Griffin, 29 N.Y.2d 91). However, any error in admitting the sketch was harmless in light of the overwhelming evidence of the defendant's guilt (see, People v. Crimmins, 36 N.Y.2d 230). The testimony concerning the means by which the defendant became a robbery suspect was enough for the jury to understand why the defendant was arrested (see, People v. Seymour, 225 A.D.2d 487).

Contrary to the defendant's contention, the Supreme Court properly declined to instruct the jury that it should consider the evidence as it related to each crime separately, as there was not a substantial likelihood that the jury would be unable to do so (see, People v. Jackson, 273 A.D.2d 253). The defendant was positively identified by each complainant in subsequent lineups. Proof of each crime was presented separately and clearly, and was easily separable and discernible in the minds of the jurors.

The defendant's remaining contentions are without merit.
