Botched Vic cop raid victim traumatised

A man whose arm was shattered in a botched Melbourne police raid can't bring himself to return to the apartment stormed by officers, who mistook him for a carjacker.

Nik Dimopoulos, 47, is out of hospital after arm and shoulder surgery but remains traumatised and isn't living at the Fitzroy apartment, raided earlier this month.

He was sleeping upstairs from gay bookshop Hares and Hyena when police busted in about 2am on May 11.

Mr Dimopoulos feared it was a homophobic home invasion and ran onto the street where he was arrested and injured.

"I doubt that he has been back there ... none of them like to be in that place alone," friend and state MP Fiona Patten told AAP of Mr Dimopoulos and his flatmates.

She said Mr Dimopoulos was being cared for by family after being released from hospital at the weekend, but was unlikely to regain the full use of his arm.

"For someone who's an arts director ... this will be the end of that career for him," Ms Patten said.

The state's corruption watchdog is investigating the incident.

The property was raided after police tracked a stolen car to Fitzroy and mistook Mr Dimopoulos for the crook.

Mr Dimopoulos's lawyer, Jeremy King, said police did not identify themselves after entering the property and the 47-year-old was considering his legal options.

"He needs time and space," Mr King said.

Ms Patten said Mr Dimopoulos was receiving trauma counselling.

"I have no reason to doubt that they were completely unaware it was police and they thought it was a home invasion," she added.

Assistant Commissioner Luke Cornelius has apologised for the botched raid, saying it was "very clear to us that police stuffed this one up".

But police union boss Wayne Gatt said widely-publicised details of the incident were wrong and the officers involved clearly identified themselves after entering the premises through a rear roller door.

"I'm not appalled by what our members did, I'm proud of what our members did. Our members went out and did their job and made an arrest as the community would expect them to do," he told radio station 3AW last week.
