Police are appealing for a member of the public who may have been flying a drone at a north-east beach to contact them in their bid to trace a missing man.
Alastair Done, a 25-year-old from Cheshire, was last seen at Balmedie on January 5.
Officers believe he may have still been in the area at 3pm after being given information by members of the public.
Alastair arrived by train in Aberdeen from Crewe at 3.51pm on January 4.
He was seen going into Aberdeen Market and was later captured on CCTV at Premier Stores in Balmedie buying food and drink.
Since then, the clothes he was last seen wearing have been found on the beach at Balmedie, around one mile north of the car park.
