Western Australia's Police Commissioner believes the introduction of body scanners in the Perth watch house and other major stations will help reduce risk of confrontation between officers and detainees over strip searches.

The Corruption and Crime Commission (CCC) has criticised WA Police over what it concluded was the unlawful use of force to strip search Joanne Martin at the watch house in 2013.

Commissioner Karl O'Callaghan has told a parliamentary committee that a large number of changes had been implemented since that incident to address the opinions expressed by the CCC.

Mr O'Callaghan said body scanners would all but eliminate the need for strip searches when they were introduced early next year.

"We're hoping that the first two body scanners will be available for use by about February or March next year," he said.

"Part of the challenge in using body scanners in Australia is that they have to be licensed by the Federal Government.

"Obviously, I'm keen to get them in place as soon as possible because its better for members of the public, but of course it's also better for police officers."

Body scanners will be first introduced at the new Perth watch house in Northbridge, and then progressively at other metropolitan stations and selected regional centres.

Better police supervision, training since CCC report

The committee questioned the Commissioner and other senior police about the police response to the CCC report into the incident involving Ms Martin, which was released in August.

The incident occurred in April 2013 when the woman was taken into custody at the East Perth watch house after being arrested for disorderly behaviour in Northbridge.

In its report, the CCC condemned the conduct of officers involved in strip searching Ms Martin, and raised concerns that it was part of a wider culture and institutionalised failure in WA Police.

After being taken to East Perth watch house, "Ms Martin found herself naked, lying face down on the floor, with a number of watch house officers seeking to restrain her, one applying hammer blows with a fist to the shoulder blade area," the report said.

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".

The committee was told police had accepted and taken action to implement recommendations from the report.

Changes included improvements in supervision, training and procedures for watch house staff, and improved electronic record keeping of decisions and actions taken by officers detaining and searching people in custody.
