I think it was on this thread that there was commentary on the incident - followup article on ABC blog:
Victoria Police has suspended an officer who was filmed during an arrest where he appeared to grab a man from behind and swing him to the ground.
The video was filmed last Wednesday at Flinders Street train station and was posted to social media during Melbourne's week of anti-lockdown and anti-vaccination protests.
The video appears to show a man speaking to two officers at the train station.
A third officer is then seen grabbing the man from behind and swinging him to the ground.
The man has both of his arms held by the officer and appears to hit his head on the ground.
Victoria Police today announced it had suspended an acting sergeant from a specialist support unit "as a result of early enquiries".
Police are still investigating the incident and are calling for witnesses, including the person who filmed it, to contact Crime Stoppers on 1800 333 000.
Video shared widely on social media
The video of the arrest has been shared across social media since it was uploaded.
Last week the Chief Commissioner of Victoria Police Shane Patton told 3AW police were reviewing the footage.
"We'll investigate that. I don't know what the full circumstances are. There's always context to everything," Commissioner Patton said.
The actions of the police officer were criticised by some of Victoria's leading lawyers.
Barrister and Liberty Victoria president Julia Kretzenbacher wrote on Twitter that it was "unacceptable" behaviour.
"VicPol have powers to use force, but they have to be exercised lawfully and safely," she wrote.
Australian Lawyers Alliance Victorian president, Jeremy King, also voiced his concern when the footage emerged.
"I appreciate that it has been a long and difficult week for police and their patience is wearing thin," he wrote.
"But this sort of conduct can never be justified.
"It is excessive and dangerous, violence from either side should be roundly condemned."
