Relatives of newspaper seller Ian Tomlinson have broken down in court after film footage of his final hours of life was shown.
The 47-year-old's widow Julia and stepson Paul King cried as a film clip was played of a medical student trying to save Mr Tomlinson as he lay on the pavement with his eyes closed.
He collapsed minutes after being hit with a police baton and shoved to the ground by Pc Simon Harwood during the G20 protests in the City of London in April 2009.
Jurors were shown footage of Harwood, 45, adopting a "strike" position with his baton as Mr Tomlinson stood with his back to him.
The footage showed Harwood among a group including dog handlers and officers in riot gear, pushing Mr Tomlinson to the ground.
