HD footage of the moment the Manchester United team bus was "attacked" outside West Ham's stadium, the Boleyn Ground, ahead their match last night.
The video, filmed shortly before kick-off, shows fans surrounding the coach, with what appear to be beer cans being thrown at it, smashing at least one of the windows.
Kick-off was delayed by approximately 45 minutes because of the trouble.
The FA has condemned the incident and West Ham United have vowed to issue life bans to those responsible.
