Officers have issued an urgent appeal to find a missing teenager from Wigan who was last seen on Friday night. Greater Manchester Police says Mark was seen in the Ince-in-Makerfield area of the town at 9.30pm on July 15.
The youngster, whose surname has not been given by GMP, is described as 5ft 10ins tall and of slim build. He has short, dark-coloured hair, along with a small scar on his right cheek.
GMP says Mark was last seen wearing a black North Face jumper with a zip, as well as black shorts, black socks and black trainers. Police say they are increasingly worried about the teenager and are urging anyone who knows of his whereabouts to come forward as soon as possible.
