A Brooklyn teenager says an NYPD transit cop bodyslammed him on a subway platform in an incident caught on videotape.Sean Pagan, 19, was waiting for a train to Coney Island at the 45th St. subway station near his Sunset Park home when he was confronted by the cop at about 8:30 p.m. Thursday. The video shows that the uniformed cop has Pagan put his hands against the wall and frisks him, but Pagan squirms and complains when he feels the frisk gets too intimate.The cop reacts by slamming Pagan twice on the ground and putting him in a headlock. The advertising sign Pagan is holding onto is torn from the wall. "I was just in shock he really did that," Pagan said. "I'm sure there are other kids who got the same treatment or worse treatment that wasn't recorded."The encounter was taped by David Galarza of neighborhood activist group La Casita Comunal de Sunset Park, who happened upon the scene.A friend of Pagan's can be heard speaking in Spanish on the recording indicating that Pagan may have jumped a turnstile.Authorities say Pagan was seen writing graffiti in a restricted area of the station.Pagan was charged with theft of services, resisting arrest, criminalmischief, making graffiti and trespassing and held overnight.By Barry Paddock / New York Daily NewsSource:
