Cops have arrested a man they say stabbed a train commuter in the arm as the victim tried to break-up a fight on a Manhattan-bound G train, officials said Saturday.
Steven Jones, 41, of Red Hook, allegedly plunged a knife into his 48-year-old victim’s left bicep when the peacemaker wouldn’t let him on the train at the Smith-9th Sts. station at 3:30 p.m. Thursday.
Jones was arguing with a group of men about to get onto the train when the victim — a complete stranger — tried to stop him from following them onto the train car.
Outraged, Jones flashed a knife, stabbed the man in the arm and ran out of the elevated train station above the Gowanus Canal, cops said.
Medics rushed the victim to New York Methodist Hospital, where he was treated and released.
Detectives quickly distributed surveillance images of Jones fleeing the station, cops said. A tipster who saw the pictures identified him by name, police sources with knowledge of the case said.
