Questions will be asked about security procedures because an armed robber absconded for a second time after he was sent to an open prison. Twenty-six year-old David Patmore had already escaped custody from the dock seven years ago. "Open prisons have existed since 1936 and they are the most effective means of ensuring prisoners are tested in the community before they are released," a Ministry of Justice spokesman said. "To release prisoners directly from a closed prison without the resettlement benefits of the open estate would undoubtedly lead to higher levels of re-offending."
