Marcus Denis Mayne escaped from the  minimum security section through an open roller door and two unlocked gates.

The 27-year-old spent almost two hours on the run and allegedly took a 16-year-old boy hostage before he was recaptured on board a yacht in Geilston Bay.

During his time on the lam, he allegedly stole $400 in property, including clothes, drinks, $25 in cash, bolt-cutters and a screwdriver.

Police charged him with stealing, destroying property, aggravated burglary, escape and assaulting a 16-year-old boy by depriving him of his liberty.

On Thursday, Corrections Minister Vanessa Goodwin confirmed that   the man was armed with a knife and was  able to escape through the facility’s vegetable processing area.

‘‘Another prisoner working in the vegetable processing facility observed the escape and notified the industries supervisor, at which time a code white response was called, including immediate notification of the escape to Tasmania Police,’’ she said.

‘‘I made clear to prison management that this was an unacceptable occurrence, and indeed prison management also recognised this. Immediate changes to procedures and protocols were put in place to prevent a recurrence.’’

The report also identified a greater need for security at the prison.

‘‘The report makes several further recommendations to improve security at the facility, and I have asked prison management to progress these immediately.

‘‘For obvious reasons it is not appropriate to release reports detailing the specifics of prison security measures.’’
