Footage shows PC Simon Harwood trying to make G20 arrest

Video footage recorded at the G20 protests in London on 1 April 2009 shows the moment PC Simon Harwood - here labelled as "Principal Officer" - tried and failed to arrest a protester for scrawling graffiti on a police carrier.

Later that day, in London's Royal Exchange Passage, PC Harwood pushed Ian Tomlinson to the ground. Mr Tomlinson, 47, who was walking home from work, suffered a heart attack several minutes after walking away from the incident.

PC Simon Harwood was found not guilty of manslaughter.
