What happened to Brit who vanished in Amsterdam's red light district nearly 35 years ago?
In October 1989, 18-year-old Jayson Duffy was in Amsterdam for a work trip. He travelled with four colleagues as part of a marketing exercise and was out drinking one night in the city's famous red light district.
But sadly, Jayson - from Coventry - would never come back home from the Netherlands and went missing after last being seen with two associates in Amsterdam's Cafe de Burgh. There has been no trace of him since that day nearly 35 years ago.
And now, after the investigation into his disappearance was reopened last year, West Midlands Police are once again appealing for information.
What do the police know?
A West Midlands Police spokesperson said: "We know he was in the bar late that night and within a couple of minutes of the last sighting of him, the people he was with noticed he was missing.
"He did not return to his hotel and there were no further sightings.
"Although Amsterdam has an extensive canal network, including directly outside the bar, nobody has ever been found and no witnesses have ever reported seeing anyone fall in at that time.
"While we cannot rule out criminal activity, there were no witnesses or evidence of anything happening to Jayson of a criminal nature."
Despite this, his case remains unsolved. He was last seen wearing a cream or white coloured crewneck jumper, blue tracksuit bottoms and white trainers. He is mixed-race with curly afro-style hair. He also had a brown marking on the white of his right eye and a scar on his right-hand index finger.
A force spokesperson added: "We are still hoping someone out there will know what happened to Jayson, and may have seen him if he returned to the UK."
Anyone who may have information about Jayson's disappearance is asked to get in touch with the force's Locate team on 0121 626 7003.
