Police searching for missing York man Ben Clarkson say they have made contact with the man seen on CCTV talking to Mr Clarkson in a nightclub on the night he disappeared.
Ben, 22, has not been seen since 3.40am on Sunday 2 March in the Layerthorpe area of York.
The 18-year-old came forward after his image was released on Monday March 11 to confirm he was the man seen in the CCTV footage.
He also confirmed he is not the man who was seen walking with Ben along Layerthorpe in the city.
Officers would still like to speak with another man, who is described as white, wearing a light-coloured jacket with dark trousers and shoes.
He walked along Stonebow, towards the Foss Islands Road junction, on the opposite side of the road to Ben. A short time later, he took the same route as Ben when they walk past National Windscreens, Layerthorpe.
Inspector Neil Drummond, of York Safer Neighbourhood Team, said: “If you could be the man who walked along Layerthorpe at the same time as Ben, I ask you to get in touch with us as soon as possible as I believe you will have noticed Ben walking across the street from you.”
Anyone with any information about the disappearance should contact North Yorkshire Police
