A 65-year-old man was killed on Wednesday afternoon after a teenager who had been ranting incoherently punched him on a subway platform in Brooklyn, knocking him onto the tracks, the police said.
A witness flagged down a police officer at the station, Jay Street-Metro Tech in Downtown Brooklyn, while bystanders jumped down and pulled the man off the tracks, the police said. The man, who did not come in contact with the electrified third rail and was not struck by a train, later died at Brooklyn Hospital Center. His name was not immediately released.
The teenager, 18, stayed in the subway station after the attack, and detectives were interviewing him at a precinct station house on Wednesday night. Charges were pending, the authorities said, and his name had not been released.
The police said that the 65-year-old man was waiting for an R train around 2:30 p.m. when the teenager came up to him. The younger man was ranting and the older man extended his arm to keep him away, witnesses told the police. The teenager walked away, they said, but then returned and punched the man.
The police were looking into whether the man struck his head in the fall, and they were waiting for the medical examiner’s office to determine the cause of death.
