An appeal has been issued for help finding a girl who went missing more than three weeks ago.

Greater Manchester Police say they're "very concerned" over the whereabouts of a 15-year-old who they named only as Katelan. In a new CCTV image, the teen - who has links to Manchester and Bolton - was seen boarding a bus.
