Police searching for missing Anstruther man Iain Marr believe he could have travelled to Ireland
Mr Marr has not been seen since he left an address in the Fife coastal town shortly before 11am on Wednesday.
Since then the 40-year-old has not been in touch with friends or family.
Inspector John Docherty from Police Scotland’s Fife Division said: “Our inquiries into Iain’s disappearance are ongoing.
“As such we are widening the scope of our search operation to include Northern Ireland and the Republic of Ireland and asking anyone who may have seen or spoken to Iain to contact Police Scotland immediately.
“Iain has been missing for considerable period of time and our concern for his welfare is growing.
“We want to know that he is safe and I appeal to Iain directly to call police, or a family member, to let us know that you’re okay.”
On Friday, police released CCTV images of Mr Marr taken at a BP petrol station on Main Street in Colinsburgh at around 11am on Wednesday.
At around 12.15pm on the same day, the distinct silver coloured Subaru Impreza he was driving, with the registration SG60 JVE, was spotted on the westbound carriageway of the M8 at the Harthill Services in North Lanarkshire.
Mr Marr is described as being around 6ft tall, of heavy build and with short cropped brown hair and brown eyes.
He talks with a soft west coast accent.
Anyone with information is urged to contact Police Scotland on 101 or speak to any officer.
