Serco has said that guards were not to blame for the escape of prisoners in Geraldton early this month.
Cameron Graham and Kelden Edward kicked their way out of a prison van at the Geraldton Airport on January 3 and were on the run for 36 hours before being captured.
Serco, which holds the $50 million-a-year contract to run WA’s court security and custodial services, previously refused to reveal if action was being taken against the guards on duty when the escapes happened, saying investigations were continuing.
However the company has now cleared its staff.
“Following each of these two escapes, our initial assessments indicated that our staff had followed procedure,” a spokesman said.
“Staff have not been stood down in either case and are not subject to disciplinary process.
“In each case we took immediate action with the Department of Corrective Services to improve security measures.”
