A woman had her finger badly broken by Perth police officers and was subject to a prolonged physical attack while she was lying naked on the floor of the East Perth watch house.

The explosive details were revealed in a Corruption and Crime Commission (CCC) report about the April 2013 incident, which also revealed how she was paraded naked in front of other officers.

The CCC condemned the conduct of officers involved and raised concerns it was part of a wider culture and institutionalised failure in WA Police.

However, Police Commissioner Karl O'Callaghan said no action would be taken against the police involved.

The incident occurred in April 2013 when Joanne Martin was taken into custody after being arrested for disorderly behaviour in Northbridge.

After being taken to the watch house, Ms Martin was forcibly strip searched and "found herself naked, lying face down on the floor, with a number of ... officers seeking to restrain her, one applying hammer blows with a fist to the shoulder blade area", a CCC report into the incident found.

Other officers also hit her with "a second also striking her, and another using such force to try and remove a ring that it caused a serious fracture of a finger".

Woman escorted past officers covered only by a blanket

The CCC said Ms Martin was escorted past male officers while in leg restraints and handcuffs, still naked and only partially covered by a blanket, and taken to a padded cell.

"There was nothing to indicate ... [Ms Martin] was a threat to any person," the report found.

"It is of considerable concern that a person could in Perth in 2013 undergo what befell ... [Ms Martin] at the watch house on the morning of April 7, 2013."

Her treatment should not be considered "normal and is not acceptable."

The officers involved in the incident, against whom adverse findings were made, were auxiliary officers Joanne Lynch, Fiona McPherson and Amy Sumner, acting auxiliary officer supervisor Sarah Whiting, and Sergeant Andrew Unsworth.

The CCC found the "excessive" force used by Ms Lynch in trying to remove a ring from Ms Martin's finger amounted to serious misconduct, as did Ms McPherson's participation in Ms Martin's violent strip search.

Ms Sumner's behaviour towards Ms Martin "was both unreasonable and oppressive", while the force used during the strip search by Ms Whiting and her action "in striking Ms Martin at least six hammer blows to the shoulder blade area" was unlawful, the commission found.

Sergeant Unsworth's failure to act on a complaint by Ms Martin about her treatment was unreasonable and a breach of trust, the report said.

The CCC attributed the incident to poor training and supervision, a failure to comply with laws, and what it described as "... inconsistencies in the legislative protections for those in police custody and internal police rules".

A video released by the CCC shows Ms Martin being brought through the reception area of the watch house.

She tells an officer she is asthmatic and "had a little bit of anxiety", when asked if she had any medical conditions.

She then walks calmly from the front reception out the back when asked.

Off-screen, she can then be heard shouting "don't" before beginning to scream.

"Don't f***ing hit me," she said. "My arm ... you're hurting me. Please help me."

She is then taken through the reception area to a cell by a number of officers.

"When you get to the padded cell, I want you to drop to your knees," an officer is heard telling the crying woman.

"Lie down," a voice said.

No footage from inside the cell has been released.

The footage appears to show officers handing her clothes out of the cell.

The woman can later be heard telling officers who check on her that she is lying naked on the ground.

A female officer says she will approach her supervisor. One officer tells the woman she needed to have a "better attitude".

The CCC suggested that the treatment of Ms Martin was part of a wider culture and "institutionalised failure".

"While individual officers concerned were, and should be, accountable for their actions at all times, the conduct in regard to ... [Ms Martin] occurred in the context of apparently similar other conduct, tacitly or otherwise," the report said.

"That this is the case is the result of institutionalised failure by WA Police and the failure of its chains of command to ensure that the law, various regulations, policies and procedures are correctly applied, and its officers and their supervisors are accordingly held to account."

The CCC said it would monitor action taken by WA Police to address the issues raised in the report and implement the commission's recommendations.

Police disagree with CCC findings: Commissioner

Mr O'Callaghan said the incident occurred in the old watch house, and since police moved to a new watch house in Northbridge, protocols had been put in place to avoid a repeat of the action.

He said he did not intend to take any action against the officers involved.

"Two of the officers are no longer with the WA police," he said.

"And the other thing I would point out is that we don't agree with all the findings of the commission on this.

"They did issue a section 42 notice and have powers to charge the officers if they want to, but those officers, the remaining officers are still at work, and given that we've moved on two-and-a-half years there is no action planned against them at this stage."

WA Police Union president George Tilbury said in a statement the union was disappointed it had taken so long for the CCC to "form its opinions".

"The CCC identified this incident and directed WA Police not to investigate," the statement said.

"We believe the Professional Standards Portfolio is best placed to investigate allegations of police misconduct.

"If they were allowed to investigate, any perceived issues would have been resolved much sooner."

WA Premier Colin Barnett said he was unhappy with the report.

"It's clearly a very serious report and it's clearly a very serious incident," he said.

"So I think the Police Commissioner will respond and the Police Minister may have something to say.

"Clearly, I'm clearly not happy with the little bit I do know about that incident."
