A MISSING WA prisoner who police had warned was “unpredictable” was found in Cockburn Central overnight - allegedly hiding under a pile of laundry.

Santana Marie Mason had gone missing from a minimum security facility in Bentley on Saturday morning.

Police had appealed for public help to find the 27-year-old but warned people against approaching her.

Police confirmed this morning a 27-year-old woman had been taken into custody overnight and charged with escaping from lawful custody. She was refused bail and is due to appear in Perth Magistrates Court today.

A 35-year-old woman from Cockburn Central has been charged with aiding an escape.

Police allege that when they arrived at her home and asked whether the escapee was there, the woman told them she wasn’t - but that a subsequent search of the property revealed that she was.

The Cockburn Central woman’s charge does not relate to physical assistance in the prison escape but instead to allegedly providing police with false information.

She will face Fremantle Magistrates Court on Friday December 29.
