Police release CCTV images of missing man Calum MacKenzie
CCTV images of man missing from his home since last week have been issued by police in their efforts to find him.
Calum MacKenzie, 41, was last seen in Alness in Easter Ross at about 13:45 on Thursday.
He was seen on CCTV at a Morrisons store in the town's Dalmore Road at 13:27 that day.
Local coastguard, RNLI and mountain rescue team volunteers have been searching Alness and nearby Invergordon on the Cromarty Firth.
Police said they were increasingly concerned for his welfare and have asked the public to check sheds, garages and other buildings.
Sightings of Mr MacKenzie have also been sought from motorists with dashcams fitted to their vehicles.
Police have appealed to drivers who were on Salvesen Crescent, Kendal Crescent or the Obsdale Road areas in Alness or the B817 shore road between Alness High Street and Invergordon between 13:00 and 15:00 on Thursday to check any footage.
Insp Alasdair Goskirk said: "We are continuing to work to establish Calum's movements from when he was last seen and would ask that members of the public review the CCTV images to see if they recall seeing Calum.
"The images show the clothing we believe Calum to be wearing when he was last seen, which are a black jacket, a light blue shirt, black jeans and black boots."
The officer added: "It has now been over four days since Calum has last been in contact with, or seen, his family. They, along with officers, are understandably worried for his safety.
"We'd continue to appeal to anyone who has seen Calum, or has any information on his current whereabouts, to contact police as soon as possible."
Mr MacKenzie is white, 6ft tall, of stocky build and bald.
