Officers from the Moray and Aberdeenshire division say they are becoming increasingly anxious to trace Sandy Gray, who was last seen by his wife at their home in Elgin around 8am on Friday, September 13.
Mr Gray has been described as being 5ft 8in in height, of medium build and with short, grey receding hair.
Chief Inspector Willie Findlay said: “We would appeal to anybody who may have seen Sandy in the Boat O’ Brig area near to the River Spey or on the Speyside Way during the late morning and early afternoon of Friday 13 September.
“We have located the car that Sandy was using at the Boat O’ Brig car park beside the rail and road bridges over the Spey, which is often used by walkers, and appeal to anyone who may have seen a red Seat Ibiza motor vehicle with the registration plate SV09 NVM in the vicinity to come forward as it may help us trace Sandy’s movements on Friday afternoon.
“We are currently concentrating our search to the Boat O’ Brig area as there is the increasing fear that he may have fallen while out for a walk and become incapacitated.”
Anybody who has knowledge of Sandy’s whereabouts or who may have seen Sandy or the vehicle in the area on Friday 13 September, is asked to contact Police Scotland on 101 or via Crimestoppers if they wish to remain anonymous.
