Police are hunting two teenagers who assaulted a Banksia Hill Detention Centre security guard, stole a vehicle and used it to smash through metal gates to escape yesterday.
It is alleged Christopher Meredith, 18, and 17-year-old Peter Robert Garlett - both considered dangerous - assaulted the guard and used a Toyota Hilux four- wheel drive to break through the centre's main gates about 10.15am yesterday.
Police said the Toyota collided with another vehicle at the intersection of Bristle Avenue and Ranford Road soon after.
Garlett and Meredith allegedly stole another Toyota Hilux, a white 2002 single cab four-wheel drive, from a shopping centre. The vehicle had a beige canvas canopy and black bullbar.
The vehcile was found in the suburb of Camillo this morning.
Acting Assistant Commissioner for Youth Justice Andrew Salter said yesterday's incidents would be "thoroughly reviewed".
Mr Salter said the Corrective Services Department was confident in security at the centre and regularly checked all security procedures.
Community and Public Sector Union-Civil Service Association branch secretary Toni Walkington said the incident highlighted security problems at the centre that the union had raised repeatedly.
Ms Walkington alleged the security guard assaulted by the escapees had been hit with a brick. She said the breakout came after other worrying incidents where other detainees had accessed the building site at the centre, thrown bricks at staff and climbed on to the roof of a building.
Garlett is dark-skinned, 170cm tall, with a medium build, brown hair and brown eyes.
Meredith is dark-skinned, 176cm tall, with a slim build, brown hair and brown eyes.
A police spokesman said the public should not approach Garlett or Meredith.Anyone who sees the white Hilux or has information on the whereabouts of the teenagers is asked to call Crime Stoppers on 1800 333 000.
