A 15-year-old boy riding a train though Brooklyn was beaten and robbed of his cellphone, shoes and even his pants during a shocking gang attack caught on video. <br /> <br />Up to five teens pounced on the 15-year-old victim after he got onto the Canarsie-bound L train at the Broadway Junction station in East New York about 3:30 p.m. Friday, cops said. <br /> <br />The teen tried to flee the train at the next stop — the Atlantic Ave./Snediker Ave. station — but his attackers grabbed him on the platform, taking his shoes, pants and cellphone, police said. <br /> <br />A startling cellphone video taken during the brawl shows the teens beating their victim, then dragging the pantless teen back onto the train, where stunned straphangers called 911. <br /> <br />The lanky teen was sprawled out in his underwear on the subway car floor as concerned commuters tried to console him and give him water, the video shows. <br /> <br />Paramedics took the victim to Brookdale University Hospital with injuries to his head and body, officials said. <br /> <br />Cops were looking for the assailants Saturday. <br /> <br />Brooklyn community advocate Tony Herbert said the attack occurred when two gangs clashed. <br /> <br />“What is happening nowadays is a group of teens will walk up to another group of teens, whether they be two or more, and ask what gang they reppin, then in a flash of a second the assault begins,” Herbert said.
