London's police force says it has suspended an officer caught on camera pushing a man who later died at a G-20 protest.
Video footage filmed by a bystander shows an officer appearing to hit Ian Tomlinson with his baton before shoving him to the ground.
Tomlinson later died of an apparent heart attack. The Metropolitan Police said on Thursday that the officer, a constable, had been suspended. His name was not released.
Britain's police watchdog has ordered a second autopsy to see whether police behavior contributed to Tomlinson's death.
Thousands of people took part in protests against a meeting of the G-20 nations in London last week. Forty-seven year old Tomlinson was walking home from work when he got caught up in the protest.
