Police are searching for two women who they want to return to prison.
Lisa Edwards, 41, was an inmate at East Sutton Park prison in Maidstone but failed to return last Saturday after she was released on a temporary licence.
Kent Police believe she could be with another woman, Alison McDonald, 48, who has been recalled to prison.
The pair have links to the Medway area.
