Fresh photographs have been issued in an effort to help trace a 22-year-old Sutherland man missing for 12 days.
Lachlan Simpson’s relatives have released a picture of him in the hope that someone has seen him and will make contact.
The Embo chef disappeared after leaving a county show marquee dance on the links in Dornoch.
The last known sighting of Mr Simpson was 1.30am on Sunday, July 26.
Police have released a photograph of a rucksack similar to one that he often uses.
The force is urging locals and businesses to check outbuildings, sheds, gardens and garages for the rucksack.
Inspector Jamie Wilson said: “We continue to see great support from the local community.
“Once again, we must say thank you to those who have helped and continue to assist us.”
Specialist search officers from Aberdeen have now joined the operation.
Tomorrow, (FRI) a police unit will be established at the Dornoch Highland Games, which takes place at The Meadows Park.
“If anyone has any information regarding the search, no matter how insignificant they may feel it to be, they can speak to an officer who will be there to provide assistance,” Mr Wilson said.
Police confirmed earlier this week that they had received information from a psychic, via a member of the public, about Mr Simpson’s possible whereabouts.
He had been expected to rendenzvous with friends in Dornoch before heading to a party in Embo that Saturday night.
Organised mass searches by volunteers ceased last Sunday after drawing a blank.
