Police are searching for a violent prisoner who absconded from an open prison near Dundee.
Samuel Boyle Stewart failed to return to Castle Huntly at 15:00 on Wednesday after being granted temporary leave in Edinburgh.

He was transferred from HMP Edinburgh to Castle Huntly in January this year, Tayside Police said.
Stewart is currently serving a sentence of five years and four months.
As well as having friends and associates in the Edinburgh area he has also travelled to London in the past, police said.
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.
Police have appealed to anyone with information about Stewart's whereabouts to contact them.
