The video, shot by someone in a passing car, shows two men attacking another man as he lies on the road. Both men repeatedly punch the victim, before one delivers a kick to the head. Others then intervene, remonstrating with the assailants who are heard to claim that the incident was sparked by someone being cut off on the busy motorway.
