Police said there remained “unanswered questions” around Mr McCallum’s disappearance.

Mr McCallum’s car, a black Ford Focus, was found near where he was last spotted in the Loch Lomond area.

He is described as as 5ft 9ins tall, with a slim build and dark brown hair.

So far, there have been no confirmed sightings of Mr McCallum. However, police said there has been two potential sightings of him in Sussex in 2017 and in the Tower Hill Underground Station in London in 2019.

Detective Inspector David Lavery, of Dumbarton Police Office, said: “We regularly review unsolved missing person cases and there have always been unanswered questions around David’s disappearance.

“There have been a number of appeals over the years, including by the charity Missing People.org and on television documentaries.

“These latest images show what David may look like now. If anyone recognises David from these images, or has any information that can help our enquiries, please contact us.

“I would appeal particularly to anyone who was wild camping in the Lochan Maoil Dhuinne area the weekend David was last seen, as well as people who have worked with the homeless community in London over the years.”

In 2007, Mr McCallum’s family appeared in a BBC One series called ‘Missing’, in an effort to uncover further information about his whereabouts.

In an interview with the Clydebank Post the same year, his sister, Susan Donaldson, said: “It is just like he has vanished into thin air. For us as a family we are getting no closure.

“Just to have nothing at all makes it very difficult.

“It is just as raw as it was from day one."

Meanwhile, his brother described the unsolved case as like “sitting with a book and we have got a final page missing,”.

“We just want to know what's at the end.”

On the 20th anniversary of his disappearance two years ago there was a fresh appeal by police trying to trace the father-of-two.

In a statement on social media, police said: “Today marks 20 years since David McCallum went missing.David was 31 when he was last seen in Clydebank, Strathclyde, on 28 March 2003. Our thoughts go out to David and his loved ones.”
