Prisoners use forklift in Perth break out

Four prisoners have used a prison forklift to break out of a Perth minimum security jail.

One teenage inmate remains on the run after he and three others escaped 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 inmates were captured after they were spotted in a car - believed to be stolen - which prompted a police chase that ended in Rivervale.

Police are still searching for Geoffrey Ninyette, 19, but have warned the public not to approach him.

Facility operator Serco issued a statement regarding the forklift, saying Wandoo has a number of pieces of light industrial equipment which are used in work and training programs.
