Tayside Police has released CCTV images of missing man Colin MacDonald.
The CCTV images show Mr MacDonald on High Street and Queen’s Bridge, Perth, before 2pm on Monday April 23.
They are the last confirmed sightings of the 48-year old.
Colin is described as 5ft 10in tall, bald, with a medium to stocky build. When last seen he was wearing a grey coloured gilet with a white T shirt underneath, grey cargo trousers, grey shoes and carrying a black Nike rucksack.
A helicopter was used earlier this week in the search for him.
Chief Inspector Ian Scott, local area commander for Perth, said: “We are growing increasingly concerned for the welfare of Mr MacDonald and we have issued these images in the hope that someone may have remembered seeing him.
“Local officers are in touch with Colin’s family and they are understandably upset and very concerned. We have carried out searches of the local area and have utilised specialist officers including air support and dog handlers in order to try and trace him.
“I would like to ask local businesses and members of the community to check outbuildings, sheds, gardens and garages for the bag, as it may have been misplaced or lost at some point.
“Anyone who knows where Colin is or who has information that could assist us in tracing him should call 101, quoting incident 3708 of 23rd April, or speak to any police officer.”
