Forth Valley Police are appealing for the public's help as part of their efforts to trace Sylvan Alexander-Short, who has been reported missing from Aberfoyle.
There are growing concerns for the 21-year-old, who lives in the town of Aberfoyle and is described as being 6ft 3in tall with a slim build and blue eyes.
He was last seen wearing the dark green Karrimor waterproof jacket (that he is pictured in), light-blue tracksuit bottoms and black Dr Martens footwear.
