PC Simon Harwood, accused of killing Ian Tomlinson, began his manslaughter trial on Monday of this week.
Harwood was filmed at G20 protests in London in April 2009 hitting Ian Tomlinson with a baton and pushing him to the ground.
Tomlinson, a newspaper seller, collapsed and later died. An inquest into Tomlinson’s death gave a verdict of unlawful killing. Inquests do not apportion blame.
The inquest also saw footage showing Harwood having altercations with various protesters on the day.
Director of public prosecutions Kier Starmer decided to press charges following the inquest.
Harwood has been suspended on full pay since the incident.
