Dangerous escapees on the run in WA

Two prison inmates who escaped from a security van at Geraldton Airport are considered to be violent and should not be approached, West Australian police say.

Cameron John Graham, 22, and Kelden Edward Fraser, 23, escaped at 1pm (WST) on Friday while on transfer from Geraldton Prison to Perth.

Both were last seen wearing prison greens and are believed to be travelling in a silver/grey Toyota Kluger registration 1DGZ 627, stolen from the airport.

"The men are considered violent and should not be approached," police said in a statement.

Graham was last year jailed for 11 years after breaking into a woman's home in Perth, threatening to murder her sleeping children and then raping her - before forcing her to drive to an ATM and withdraw cash.

Perth District Court was told the woman and her family had since moved overseas to try escape the trauma of the attack.

Graham is described as being 170cm tall, of dark complexion, medium build, with brown eyes and short brown hair.

Fraser, who is on remand, is 180cm tall, of dark complexion, medium build and with brown eyes and black hair.

Both were last seen wearing prison greens.

Anyone sighting the vehicle or any person they believe to be either of the men should call police on 131 444.
