A Melbourne doctor has alleged police assaulted her after she sought to help a barely conscious and bleeding man who was surrounded by officers in April 2018 — and that they then covered up the brutality.

Kim Proudlove, a stepmother of three who specialises in helping people with brain injuries, has spoken publicly about her ordeal and frustration with the Victoria Police complaints system.

Dr Proudlove does not fit the profile of the Victorians most likely to report an adverse experience with police — vulnerable or marginalised people less able to navigate the police complaint system.

She is an experienced doctor with a track record of helping people in need, including a cyclist and pedestrian badly injured in traffic accidents.

But when she tried to help a bleeding and apparently unconscious man surrounded by police, Dr Proudlove has alleged she was subjected to police brutality; after she filmed some of the alleged assault on her phone, she says police deleted it; and after she complained to police internal affairs, she was told by police they were considering charging her with resisting arrest.

Dr Proudlove's story is striking for another reason — her alleged assault occurred just 19 days after a major police brutality scandal was exposed.

In April 2018, 7.30 and The Age revealed explosive CCTV vision of police allegedly assaulting a Melbourne disability pensioner during a mental health welfare check.

That scandal prompted the charging of several officers along with widespread calls for reform of the police complaints system, calls that were later backed by a Victorian parliamentary committee.

Dr Proudlove's confrontation with police began just after 9:00pm on April 22 in Flinders Lane in Melbourne's CBD, after she noticed a man lying in the foetal position in a doorway, bleeding and barely conscious.

Within minutes, it would be Dr Proudlove who was bleeding.

She told 7.30 and The Age she approached the police surrounding the bleeding man and introduced herself as a doctor able to provide aid.

"I was very concerned by the large pool of fresh blood, and that no-one was attending to him," she said.

She says police told her to go away, that an ambulance had been called and that the man's injuries were self-inflicted.

"I told them regardless of it being self-inflicted, the bleeding should be stopped with basic first aid while waiting for an ambulance. He wasn't moving and wasn't talking," she said.

Dr Proudlove said after she insisted the man needed help, police officers shoved her against a wall. After she began filming the police on her mobile phone, she says one of the officers attacked her.

"There was an older policeman that came towards me, violently threw me to the ground, put my hands behind my back, and repeatedly punched me in the head," she said.

"I kept asking them to stop and told them that they were hurting me.

"I had a police officer put his weight into the back of my knee, which also was very painful.

"They handcuffed me then picked me up and took me to a police van and put me in the back."

Police confiscated her phone but returned it to her in the back of the van, where Dr Proudlove discovered that video she had recorded had been deleted.

After officers dropped her home in a police van, Dr Proudlove's husband raced her to hospital.

"My right ear needed tissue glue to close the wounds, I had a swollen and bruised lip, I had a bump on my head, my knee was extremely sore causing me to limp, and I had multiple other bruises and abrasions all over my body … I was also in shock," she said.

Medical scans confirmed that Dr Proudlove's knee was badly damaged. She had suffered a tibial plateau fracture and ACL rupture.

Police investigation underway

Dr Proudlove complained to the Police Standards Command about her treatment within hours of her ordeal. After this, she was told she was under criminal investigation for resisting arrest and may face serious charges.

In December, police told Dr Proudlove she would not be prosecuted.

In a statement, a police spokesperson said the case was subject to "an active Professional Standards Command investigation".

"The Senior Constable and Sergeant involved in the alleged incident have been transferred to other duties while the investigation is taking place," the statement said.

"We are unable to provide any further information as the investigation is ongoing."
