New York City police are questioning a suspect in the death of a subway rider who was shoved onto the tracks.

New York Police Department spokesman Paul Browne says investigators recovered security video showing a man fitting the description of the assailant working with street vendors near Rockefeller Center.

Police went there Tuesday and took him into custody.

Ki-Suck Han of Queens died shortly after being hit by a train Monday at the Times Square subway station.

Police say he tried to climb a few feet to safety, but got trapped between the train and the platform’s edge.

Subway pushes are unusual. Among the more high-profile cases was the January 1999 death of Kendra Webdale. A former mental patient admitted he shoved her to her death.
