Concern after pensioner vanishes on evening walk
Police are becoming increasingly concerned for the wellbeing of a pensioner who has been missing from his home on Arran since Tuesday.
John Smith, who is 77 and from Machrie, was last seen walking east near the village's golf course at 18:10.
Officers believe he was going to visit a friend who lived a few miles away, but never arrived.
He remains missing despite a large-scale search involving police, Arran Mountain Rescue, the RAF and RNLI.
Mr Smith is described as being 5ft 4in tall and having a slim build. When last seen he was wearing a dark jacket, dark trousers, a woolly hat and brown hiking boots.
Insp Christine Boyd said local bus and taxi firms had been urged to look out for him, while members of the public have been asked to check gardens and out-buildings.
She said: "A number of days have passed now since Mr Smith was last seen, and so far we've had no confirmed sightings of him since.
"He had said to the neighbour who last saw him that he was going to see a friend in the Shiskine area of the island. We do not know if he arranged a lift or planned to walk, but he did not get to his friend's house.
"Mr Smith is a vulnerable man who has had some health issues recently and is of poor mobility, so for him to be away from his home for this length of time is very unusual. He also requires to take daily medication, which we don't believe he has with him."
Ms Boyd said search efforts so far had included specialist resources from Police Scotland including air support, police mountain rescue and support unit search teams, and help from Arran mountain rescue, the RNLI, RAF and the Coastguard.
She added: "We have also been assisted by VisitScotland, local businesses and the whole community of Arran, and we are all working together to find Mr Smith."
