An 18-year-old man has allegedly impersonated a police officer and worked at the East Perth Watch House unchallenged.
This morning police Inspector Bill Munnee confirmed the security breach.
He told <a rel="nofollow" href="http://www.thewest.com.au">www.thewest.com.au </a> that the man had been charged and would face court later this month.
Insp. Munnee said police would not comment on the breach until an investigation was complete.
"There is an ongoing investigation," Insp. Munnee said. "We believe people may be helping the person inside the watch house."
`Last night, the ABC revealed an 18-year-old man obtained a police uniform and worked on several occasions at the watch house in East Perth before being detected.
He had a full police utility belt, complete with handcuffs, police issue baton and holster, and was apparently able to work in the watch house unchallenged.
It is not clear if the impersonator had direct contact with prisoners or was able to access police computers while he was in the building, ABC reported.
Shadow police minister Michelle Roberts told ABC TV questions need to be answered immediately.
"This is truly frightening and it points to a major systems breakdown," she told ABC Radio. "It's an incredible breach of security and some questions need to be answered immediately."
Police Union vice president Denis Hayden said the union wanted assurances that no officers' personal details had been compromised.
"I believe that they've got a right to feel very, very insecure," Mr Hayden told ABC Radio. "If he's accessed them in anyway I've got serious concerns about our own people's security."
A spokeswoman for Police Minister Rob Johnson told ABC Radio the Minister had been briefed about the investigation, but that it was inappropriate for him to comment.
