Detectives have released this CCTV image of a boy they would like to speak to after a man was stabbed while waiting in a queue at Manchester's Piccadilly Bus Station.

Shortly after 10.15pm on Wednesday, October 15, the victim, a 19-year-old man was waiting with friends for the 216 bus to go to Ashton.

As the group were getting on the bus the offender approached them and an argument broke out. The offender then produced a knife from his pocket and stabbed the 19-year-old in the arm. The offender then climbed onto the bus, before leaving from the emergency exit.

The offender is described as mixed race, approximately 15 years old, 5'6'' tall and had dreadlocked hair swept tightly across his head.

Police are appealing to anyone who may recognise this boy, or who may have any further information about this incident, to contact Bootle Street CID on 0161 856 3240 or Crimestoppers anonymously on 0800 555 111.
