Detectives are concerned for a backpacker who left a caravan park without his belongings.
The man, who may be using the surname Storrier, left the Milton of Fonab Caravan Park in Pitlochry, Perth and Kinross, about 11:00 on Monday.
He arrived last Saturday and, after staying two nights, paid for a third before disappearing.
Staff at the site later discovered he had left his rucksack and sleeping bag behind.
Police have released CCTV stills of the man and images of his belongings.
Insp Kevin Chase said: "I am appealing for the wider community to see if they can identify the man in our picture."
He is described as white with a tanned complexion, of stocky build and is believed to be in his 40s.
The man was wearing a white t-shirt, blue jacket and jeans and possibly has a tattoo on his left arm.
