"Significant questions" remain about the behaviour of a police officer who was cleared today of the manslaughter of Ian Tomlinson during the G20 protests, the police watchdog said.
The Independent Police Complaints Commission's deputy chairwoman, Deborah Glass, ordered that Pc Simon Harwood will now face Metropolitan Police disciplinary proceedings in public.
Mr Harwood hit 47-year-old Mr Tomlinson with a baton and pushed him to the ground on the fringes of the G20 protests.
The father-of-nine walked 75 yards before he collapsed, and died later in hospital from internal injuries.
It can now be reported that Mr Harwood faced a string of allegations about his behaviour before he came across Mr Tomlinson.
Ms Glass said it was "staggering" that Mr Harwood managed to medically retire from the Met Police while facing disciplinary proceedings for an alleged road rage incident - and despite this was later re-employed by the force as a police officer specialising in public order.
She added: "It raises considerable concerns about their vetting procedures."
