The 39-year-old victim was dragged underneath the train, according to law enforcement officials. The victim has not been identified. They were found in the East River tunnel of the seven train on the Queens-bound side just outside the station, the Metropolitan Transportation Authority said. Service on the 7 line was suspended for hours during the emergency response.
