The 51-year-old woman was on leave for mental health issues from the force's integrity unit Inspector Thomas said station was in "state of chaos" night of woman's arrest

Inspector Bruce Thomas also conceded that the woman's dignity was not considered by junior officers in Ballarat, who left her half-naked in a police cell for hours after a shower and without a blanket.

"It's concerning," he said.

The Independent Broad-Based Anti-Corruption Commission (IBAC) is investigating serious misconduct allegations against Victoria Police officers in Ballarat who are accused of brutality.

One of the allegations centres around the treatment of a 51-year-old woman who was taken into custody in January last year for being drunk in public, and was later discovered to be an officer at Victoria Police's Professional Standards Command.

Graphic security footage showed the woman, who was on leave for mental health issues at the time, being kicked and stomped on by officers while she lay handcuffed and prone on the floor of a police cell.

The woman was also pepper-sprayed after a scuffle with officers, and was thrown in the shower while still handcuffed, before being left in her cell half-naked and wet.

After arriving at Ballarat station on the morning after the incident, Inspector Bruce Thomas checked on the woman, who said she was cold and complained about bruising on her legs.

He conceded that it was concerning she was left half-naked.

Inspector Thomas told a junior officer to give the woman clothing, a blanket and a cup of tea.

By that time, he said she was "compliant".

"She was certainly affected but I wouldn't call her drunk then," Inspector Thomas said.

"She actually called me sir."

Officers treated colleague with 'uncaring attitude'

Counsel assisting IBAC Jack Rush QC put to Inspector Thomas that the woman was treated with an "uncaring attitude" until he intervened.

"For a police officer with mental health issues to be left in the cells lacked proper care and consideration," Mr Rush said.

IBAC commissioner Stephen O'Bryan QC said he had the sense that no-one took charge on the evening the woman was taken into custody.

"In other words, everyone is thinking that somebody else can do that — [that] it's not my job," Mr O'Bryan said.

"Nobody actually properly took charge until you arrived.

"It was a state of chaos in the police station," Inspector Thomas said.

" I think the situation needed some leadership."
