Cops are trying to identify the baby-faced teens caught on wild video trashing an NYPD car in Union Square on Friday when Twitch star Kai Cenat’s unlicensed PS5 giveaway erupted in rioting — a melee City Hall blamed partly on “outside agitators.” Police on Sunday released photos of six of the eight troublemakers estimated at between 14 and 18 years old who kicked, jumped on and danced atop a parked department car during the violent mayhem, which left at least seven people injured, authorities said.
