Matter of Dysean R.

Order of disposition, Family Court, Bronx County (Sidney Gribetz, J.), entered on or about March 6, 2015, which adjudicated appellant a juvenile delinquent upon his admission that he committed an act that, if committed by an adult, would constitute the crime of criminal possession of a weapon *605 in the second degree, and placed him with the Office of Children and Family Services for a period of 18 months, unanimously affirmed, without costs. The disposition was the least restrictive alternative consistent with appellant’s needs and the community’s need for protection (see Matter of Katherine W., 62 NY2d 947 [1984]). The delinquency adjudication was based on appellant’s firing a handgun in a store while using a store employee as a shield during an altercation with other youths. Appellant had a prior record of delinquency that included, among other things, another adjudication arising from his firing shots at other persons, as well as violation of probation. Other factors included appellant’s gang activity, and his bad behavior while in custody. The court properly exercised its discretion when, at the dispositional hearing, it qualified a police officer as an expert in identifying and interpreting gang activity through the use of social media, because the officer’s training and experience provided a sufficient foundation (see People v Siu Wah Tse, 91 AD2d 350, 353 [1st Dept 1983], lv denied 59 NY2d 679 [1983]). In any event, the expert testimony was only one of many factors that led to the disposition. Concur—Sweeny, J.P., Renwick, Moskowitz and Gische, JJ.
