A two-day police search ensued earlier this month after Bradley John McIntosh-Narrier (27) shrugged the watch of Serco guards while using a toilet at the campus on January 17.
The guards locked McIntosh-Narrier in the bathroom, denying him access to hospital corridors, but he climbed through the roof before allegedly stealing a vehicle from a woman in the carpark.
A hospital spokesman said management and staff had ‘well-rehearsed procedures’ in place had the situation worsened inside the campus.
‘Staff receive regular training to enable them to manage difficult situations, including potentially aggressive patients,’ he said.
‘This incident occurred relatively quickly. Most patients and staff were unaware and the Emergency Department functioned as usual throughout,’ he said.
‘We continue to work with police and Serco as they progress their investigations.’
After the incident, Corrective Services Commissioner James McMahon issued a directive for all hospitalised prisoners to be restrained to a fixed object if needing to use the toilet. If it was not possible to fix the prisoner to an immovable object, the person would be chained to a guard via a restraint under the toilet door.
Mr McMahon said it would be an interim measure until the incident had been fully analysed.
McIntosh-Narrier faces 29 charges. Police allege he committed a number of burglary, vehicle theft, armed robbery and reckless driving offences spread across Joondalup, Armadale, Kelmscott and Champion Lakes during his escape.
He was remanded in custody after facing Perth Magistrates Court last Thursday and is expected to reappear on February 5.
