Police in New York are hunting for a man who pushed a 58-year-old fellow passenger into the path of an oncoming subway train.

The attacker shoved Ki-Suk Han onto the track as the train was pulling into the station at 49th Street near Times Square, a police spokesman said.

A bystander filmed the argument between the two men and handed the video in to police, part of which can be viewed at NBC News.
