THE BRONX - The search is on for four suspects involved in an altercation that resulted in an NYPD officer being pushed onto subway tracks.

Authorities say the incident happened early Sunday morning just after midnight at the Parsons-Archer Avenue E station in Jamaica, Queens.

Surveillance video shows the four suspects walking through the service gate instead of the turnstiles. When two officers tried to stop them, one of the suspects pushed one of the officers onto the tracks.

He was helped up by his partner, and the suspects ran off.
