Police are appealing for information in an effort to trace Stuart Eddison who has been missing from his home in Edinburgh since Thursday, May 28.
The 54-year-old was last seen in the Morningside area shortly after 10.30 a.m. and was believed to have entered a taxi.
Since then, he has not been in touch with friends or family and police are growing increasingly concerned for his welfare as he has a number of health issues that require ongoing attention.
Police say Mr Eddison has strong links to Fife, particularly in the Kirkcaldy and Glenrothes areas.
Officers are conducting various lines of enquiry and are keen to hear from the taxi driver in Edinburgh who may have picked up the man.
Stuart is familiar with the Gorgie area and may be in the vicinity.
Anyone who has seen Stuart or has relevant information on his whereabouts is asked to contact police immediately.
He is described as white, around 5ft 10in tall with short brown/grey hair and has a large build. He was wearing a grey t-shirt, grey tracksuit bottoms and brown boots.
Sergeant Murray Tait of Police Scotland said: “It is now more than 24-hours since anyone has seen Stuart and we are keen to establish his whereabouts as soon as possible and ensure he is safe and well.
“Anyone who believes they have seen him since Thursday morning, or has information that can help us find him, is asked to contact police immediately on 101.
“In addition, I would also urge Stuart to get in touch with friends, family or the police and let us know he is safe.”
