James, who is of slim build and 6ft 2in tall, has short dark hair and stubble and blue eyes. He was last seen wearing a pair of dark blue tracksuit bottoms, a dark Nike t-shirt, black and white trainers and a dark blue jacket with a fur-edged hood.
He is known to have links to the Crown Lane area of Horwich, as well as Blackrod and Little Hulton.
I've been asked by James' very worried family to post this appeal - if you have any information, please call the police on 0161 856 5761.
