A full shoreline search for a pensioner with dementia is currently ongoing on the Isle of Raasay.
Police have also issued a plea for anyone with dashcam footage to review it, as well as to check sheds or outhouses for missing man, Alistair Lovie.
The 72-year-old man was last seen walking at a disused mine area north of Inverarish on Sunday 31 March.
He is described as 5ft 10, medium build with brown hair and blue eyes. When last seen he was wearing a black jacket, jeans, a black cap, a blue shirt and a red jumper.
Coastguard Rescue Team members from Stornoway, Ness and Bragar on the Isle of Lewis, as well as Portree RNLI, HM Coastguard helicopter and ground resources, Skye Mountain Rescue the Search and Rescue Dogs Association, Scottish Fire and Rescue and police have all joined the search.
Stornoway RNLI lifeboat was tasked this morning (Monday 1 April) to take available members of Lewis coastguard rescue teams to Raasay to assist with the search, as Isle of Skye teams were searching throughout the day yesterday and some have stood down for rest.
Inspector Bruce Crawford said: "As times passes we grow increasingly concerned for Alistair and we know this is a feeling shared in the local community on Raasay.
"Alistair has dementia and it is considered possible that he may have become confused while out walking.
"He was last seen close to a disused mine north of Inverarish but he is physically fit and walks regularly so I would urge people on Raasay to be aware and to report anything at all which may be able to help with tracing him.
"I would also urge anyone with a shed or outhouse on their property where Alistair could potentially sought shelter to thoroughly check these and let us know of anything which seems out of place.
"We would urge anyone on the roads of Raasay to be vigilant and to review any dashcam footage you may have.
"I would also like to extend our thanks to the local community and the Red Cross for their support provided to everyone involved in the search."
Anyone with any information is asked to get in touch quoting incident number 2548 of Sunday, March 31 or speak with any police officer.
