The heartbroken dad of a missing Scots man has urged anyone with information to come forward and 'end this nightmare' as the eight year anniversary of his disappearance approaches.
Allan Bryant vanished November 2, 2013, on a night out in Glenrothes, Fife aged just 23.
Parents Allan senior and Marie have never given up hope of finding out what happened to their son.
Despite one of the biggest missing person searches ever undertaken by police in Scotland, and a tireless campaign led by his family and their supporters, no trace has ever been found of him.
The young man, who would now be in his 30s, was last seen leaving the Styx nightclub in his hometown in the early hours of November 3, 2013 - the club is only 10 minutes from the family home.
Dad Allan Senior has long suspected people in the local community have information on the disappearance that has not been shared with police.
He shared a memory of his son being 'so happy' the night he went out and then disappeared for years beginning the family's 'living hell'.
Allan said: "Please if anyone has any information about our missing son Allan no matter how small or insignificant you may think it is please contact the police... don't put us through another year with not knowing what has happened to our son Allan the people who know what has happened to Allan can end this nightmare for my family - all you have to do is speak up.
"Our son Allan was only 23 when he went out for a good time with his friend's on Saturday the 2nd of November 2013 around 8.30pm we never thought for a second that would be the last time we would ever see our beautiful son Allan again.
"Allan was so happy that evening when he left our home to go out for a good time the unknown and not knowing what has happened to Allan is the worst thing imaginable for any family to go through it's a living hell not knowing what has happened to Allan.
"The last sighting of our son Allan is on CCTV footage showing Allan leaving Styx nightclub at 2:02am on the 3rd of November 2013 Styx nightclub is located in Glenrothes.
"We never knew what was going on after we found out Allan was missing we where knocking on Allan's friend's doors, dealing with the police, making phone calls and doing everything possible to find our son Allan.
