Perth prison escapee still on the loose

A prison escapee is still on the run after he and three others broke out of a Perth minimum security jail.

Police are still searching for Geoffrey Ninyette, 19, who along with his prison mates used a forklift to escape the Wandoo Reintegration Facility in Murdoch at 8.30pm on Friday.

After fleeing the prison the men allegedly assaulted a man at sporting complex in Leeming while trying to steal his car keys.

A police dog later tracked one of the escapees to the backyard of a nearby property where he was taken into custody.

Another two were captured after being spotted in a car - believed to be stolen - which prompted a police chase that ended in Rivervale.

The public is being warned not to approach Ninyette.
