Fresh appeal over missing inmate Samuel Stewart
A violent prisoner on the run from an open prison could be in the Edinburgh area, police have said.
Samuel Boyle Stewart failed to return to Castle Huntly jail last Wednesday after being granted temporary leave in the city.
The 47-year-old has also travelled to London in the past, Tayside Police said.
Stewart was convicted in August 2009 of a serious assault that left his victim permanently disfigured.
He is serving a sentence of five years and four months and was transferred to Castle Huntly from HMP Edinburgh in January 2011.
A spokesman for Tayside Police said: "It is almost a week since Samuel Boyle Stewart failed to return from leave to Edinburgh.
"Efforts to trace him have so far proved unsuccessful and officers remain determined to trace Stewart and return him to custody."
Stewart is known to have friends and associates in Edinburgh.
He is described as being 5ft 8in (1.73m) tall, of medium build, with brown hair, green eyes and a fair complexion. He also has tattoos on both arms, which include the word ''Mother'', a panther and an eagle.
