At 4.50mins in to this clip an officer is clearly seen smacking a protestor across the head with his shield. At 7.49mins in an officer punches a protestor in the face.

GRAPHIC new video evidence showing a policeman hitting a protester with a shield during the G20 demonstrations in London is being released by The Sunday Times today.

Lawyers have included this and another film of a policeman punching a man as part of a dossier alleging 10 serious assaults. It will be passed to MPs.

Footage filmed at the Climate Camp protest on April 1 shows an officer in riot gear punching a man hard in the face as a crowd retreats from a police line.

A second video shows Alex Kinnane, 24, an IT technician from London, being hit on the back of the head with a shield by an officer in riot gear. In both cases the victims appear to pose no threat to the officer.

The evidence has emerged after a second postmortem examination on the body of Ian Tomlinson, 47, found he died of abdominal bleeding rather than a heart attack after being hit by a police officer.
