The police chief in Bridgeport, Conn., the state's largest city, moved three officers to desk duty after a video appeared on YouTube in which they stomped on and repeatedly kicked a man after a stun gun had already rendered him inert, reported the Associated Press.

The video is from May 2011. It was published on YouTube on Jan. 6, although it was only recently brought to the police chief's attention.

An internal investigation has been launched.
