Concern is growing for a missing hillwalker who was last seen six days ago.
The search for missing Dornoch man Stuart Campbell, who was reported missing in Sutherland, is ongoing as police renew their appeal for information.
The 33-year-old was reported missing on Monday by his family, two days after he travelled to go hillwalking.
His car, a red Suzuki Swift, registration SY08 OFA, was found at a car park most regularly used by walkers accessing Ben Loyal to the south of Tongue.
Extensive searches have been ongoing in the area involving the Assynt and RAF mountain rescue teams, SARDA and the HM Coastguard helicopter.
Mr Campbell is believed to have travelled to the area with the intention of going hillwalking, although it is not known what route he intended to take.
Officers leading the search are urging any walkers in the area to remain vigilant.
They say they are keen to speak to anyone who was in the area last weekend.
Inspector Kevin Macleod said: “It is extremely concerning for Stuart to have been out of contact with family and friends for this long.
“It is very important that any walkers who were on Ben Loyal or in the surrounding area last weekend to think back and let us know if they may have seen Stuart.
“Even if your information seems small or insignificant it may be helpful to our search.
“I would also urge workers in the area this weekend to remain vigilant and report anything which could be of note.”
Stuart is described as being 5ft 6in tall and of slim build with brown hair.
He is believed to have been wearing a hooded green Berghaus jacket with a red zip and he is likely to have been carrying a black North Face branded rucksack.
Anyone with information about Stuart’s whereabouts should contact Police Scotland on 101.
