Brawl at UK prison sees out of control inmate flatten guard to floor as other prisoners cheer
A prison officer was punched to the floor by a violent inmate - as other prisoners cheer him on.
Footage shot in a UK prison shows the prisoner burst out of his cell and square up to two guards who raise their fists in a boxing stance.
He lashes out at one of the guards, smashes him in the face and knocks him to the ground.
As excited inmates cheer, other officers - none of whom appear to have any defensive equipment - rush in and eventually restrain the man.
