'Unruly' passenger is escorted out of plane by police

Footage has emerged of Tucson Police escorting a man out of a Delta Airlines plane in Tucson, USA.

The video, shot by one of the passengers on Thursday, shows a police officer asking a man to follow him out of the plane.

The man can been seen leaving the aircraft and the police officers discussing with a man who appears to be his guardian.

According to reports, the flight going from San Antonio to Los Angeles was diverted when the passenger became "disruptive" and refused to sit down.
