Fears are growing for a Scots grandfather who has vanished whilst on a solo holiday to Thailand. David Goldthorpe had recently retired and had treated himself to the break in south east Asia.

But he failed to check in for the first leg of his flight home sparking a police investigation. The 65-year-old flew out to the Thai capital, Bangkok, on Friday, April 12.

He stayed there for a week before heading onto the beach island of Phuket. The last time his family had any contact with Mr Goldthorpe was on Wednesday, May 1.

He had been due to board a flight to the Qatari capital, Doha before picking up a connection to Edinburgh last Monday but he never made it. His family described his disappearance as "out-of-character" and told how they are "worried sick".

Mr Goldthorpe's daughter, Hayley has been posting in expat groups on Facebook, appealing for help and sharing his photograph. His daughter-in-law Kate Goldthorpe told the Daily Record: "We're concerned and eager to locate David. David is 5'8", 65-years-old, and has been on holiday in Thailand. He is single and had recently retired, so, just wanted a holiday."

She added: "He was booked on a flight to Doha on Sunday morning but police confirmed he was unfortunately not on that. It is not normal for him to not contact his daughter, Hayley. We are cooperating with Police Scotland to try to locate him. Any information or sightings should be directed to Police Scotland or the British embassy in Thailand."

Another relative posted on Facebook: "After some odd messages and then silence, we haven't heard from our uncle for five days. He has been on holiday in Thailand but police confirmed he never made his flight home. Please share as we are incredibly worried about him."

A Police Scotland spokesman said: "Officers are making enquiries following a report of concern for a Scottish man who is understood to have travelled to Thailand."

A spokesman for the Foreign, Commonwealth and Development Office, said: "We are in contact with the family of a British man who has been reported as missing in Thailand."
