We are appealing for help tracing Georden Williamson who has been reported missing from his home in Shetland.
The 26-year-old has not been in contact with his family since late October and was last seen in the Stranraer area in Dumfries & Galloway.
While this is not out of character, he is considered to be vulnerable and officers are keen to ensure his welfare.
Given the passage of time it is possible that Georden may have travelled more widely.
He is described as being around 6ft 2in tall and well built with shoulder length curly brown hair and a beard.
He habitually wears a knitted cap, a black puffer jacket and an old pair of jeans with boots and trainers. He is thought to have a guitar in his possession.
Anyone with information which could help can call 101, quoting reference NL1554/18.
