West Australian police described a man they arrested and charged as a “cerebrally challenged waste of skin” in a public post on the division’s official Facebook page.

The lengthy post was published on the South East Metro District Facebook page on Tuesday morning, detailing an incident involving a 24-year-old man allegedly driving a stolen car containing non-prescription drugs. He tried to evade police.

The public Facebook post has since been removed.

It is understood the police officer who wrote the post is simply being reminded to “use a more professional tone” in future and will not be disciplined further.

The accused was found by a police dog, and “with a noise like a terrified piglet and the face of someone trying to pass a pine cone, he grudgingly surrendered and was led whimpering to a waiting police van,” the post read.

The accused, who is yet to face court, was “mewling like a two-year-old” after being bitten by the police dog, the post also read.

“Our criminal genius has matching bite marks on both legs now. Another police dog gave him a friendly munch recently,” the post read.

The author ended with: “police officers are indeed fated to spend just a little bit of time with each of the stupidest people on earth.”

A police spokesman said officers were encouraged to use a friendly, semi-formal style on social media.

“In this case, the officer was over-exuberant in the language used and we’ve since removed the post for this reason,” he said.

“Police officers understandably become frustrated sometimes by the behaviour of repeat offenders.”

WA police has about 180 social media accounts to keep communities informed, the spokesman said, with hundreds of officers posting to Twitter or Facebook to large audiences.

He said officers with Facebook access were trained in using social media as part of their duties and have access to guidelines.
