Police have appealed to walkers and motorists in Glen Shiel for sighting of a missing walker.
Roger Fletcher was believed to have set off to walk in the Dornie area about 8.30am on Sunday.
The 77-year-old had been staying at holiday accommodation at Bundalloch. Officers said they believed he had headed out for a walk around the Camas-luinie or Bundalloch area. He failed to arrive at the point he was due to be picked up.
But police said they have now received information that a man in his 70s or 80s was spotted on the main A87 road through Glen Shiel, about four miles (6km) west of Cluanie. The man was walking with two poles and was wearing outdoor clothing and was seen about 7pm on Sunday.
Kintail Mountain Rescue Team was joined in the search for Mr Fletcher by members of the RAF MRT, Search and Rescue Dogs Association handlers and animals, along with police dogs and officers.
A Police Scotland spokesperson said: “Police and partners are conducting searches of the area and keen to make contact with the man and anyone who walking or driving in the area to establish if they can assist enquiries.”
Officers have also asked residents and visitors to check gardens, outbuildings and sheds in case Mr Fletcher has taken shelter.
The spokesperson said: “Police are increasingly concerned for Mr Fletcher’s welfare and urge anyone who saw him in the area since Sunday to make contact via 101.”
Police said he walks with a stoop and uses two walking poles to assist him. He has white hair and wears glasses. It understood he may have a small khaki-coloured rucksack with him.
