Cops are looking for a teen who was videotaped attacking a deliveryman in Harlem while trying to steal his Chinese food.

The video shows the teen lunge at the man in a lobby of the Wagner Houses at 445 E. 120th St.

A group of adults urges the youth to “punch” and “rob” the worker, as seen in the video posted on the Web site WorldStarHipHop.com.

The teen then kicks over the food and the worker throws a punch at him.

Cops said it’s not clear when the incident took place because the deliveryman did not call 911 at the time and there is no time stamp on the video.
