A boy, thought to be just 11-years-old, is being hunted by British police after a woman was sexually assaulted at a railway station.

The incident happened at Stockport station in Manchester at around 3.45pm on Friday June 24th.

Detectives have said the suspect laughed as he left the scene before returning and spitting at station staff.

PC Rebecca Swift said: "The victim was waiting with her boyfriend in the booking hall of the station when she was inappropriately touched by a young boy who then left the station laughing."

"He returned a short while later and began messing around by the ticket barriers at the Edgeley side of the station."

"Station staff asked him to leave and he responded by spitting at them. A saliva sample was collected following the incident, and officers are now working to try to identify the boy."

The boy is described as white, about 11, with short dark hair, and was wearing a black bubble jacket with a hood, black trousers and black trainers.
