ORDERED that the order of disposition is affirmed, without costs or disbursements.
The appellant waived his right to a probable cause hearing by failing to request one at his initial appearance (see, Family Ct Act § 325.1; Matter of Brian H., 161 A.D.2d 832). Although the Family Court should have informed the appellant of his right to remain silent at his initial appearance, this error was harmless, since the appellant, who was represented by counsel, did not make any statements or admissions (see, Matter of Mark J., 259 A.D.2d 40).
Viewing the evidence in the light most favorable to the presentment agency (see, Matter of Darryl W., 275 A.D.2d 792), we find that it was legally sufficient to establish beyond a reasonable doubt that the appellant committed an act, which, if committed by an adult, would have constituted the crime of robbery in the first degree (see, Penal Law § 160.15). Moreover, upon the exercise of our factual review power, we are satisfied that the Family Court's fact-finding determination was not against the weight of the evidence (see, Matter of Edwin B., 266 A.D.2d 210).
The appellant's challenge to the Family Court's disposition is academic, since he has completed the placement (see, Matter of Crandell M, 266 A.D.2d 548).
The appellant's remaining arguments are either unpreserved for appellate review or without merit.
