Allan Bryant disappeared on a night out with friends in his hometown of Glenrothes in Fife in 2013.
The 23-year-old was last seen on CCTV leaving the Styx nightclub, less than a mile from his house. No trace of him has ever been found since.
While he is still classed as a missing person, Allan’s family believe he has come to harm. A decade since his disappearance, they continue the fight to keep his name in the public eye.
This is their story.
