The court's finding was based on legally sufficient evidence and was not against the weight of the evidence. In a subway station, after appellant repeatedly and noisily banged on a pay phone, causing a disturbance, appellant refused to comply with the officers' directives to leave the station, screamed, cursed, flailed her arms, and struggled with the officers. The officers were attempting to maintain order in the station, which was an official police function, and appellant intentionally obstructed that function through "physical force or interference" ( see Penal Law § 195.05; Matter of Davan L., 91 NY2d 88; Matter of Shannon B., 70 NY2d 458; Matter of Darnell C., 305 AD2d 405).
