Police Scotland said "extensive inquiries" are being carried out to trace him, but they have so far been unsuccessful. Officers are now appealing for information from the public to help find the missing man.
He is described as being white, 6ft and of medium build with brown hair.
He has a distinctive scar on his right arm. When he was last seen he was wearing dark-coloured jeans and a shirt.
Detective Inspector Craig Willison, of London Road police office in Glasgow, said: "Mr Halton was due to attend court on January 15 but failed to appear and has not been seen since, although further inquiries revealed a sighting of him in Cairnryan on Thursday January 9 where he was boarding a ferry bound for Belfast.
"I would ask anyone who has seen Mr Halton, or who has any information regarding his whereabouts, to contact Police Scotland. I would advise that no one approaches him, but rather contact police immediately."
