A girl waiting at a bus stop in Northampton was held, punched and spat by a gang during an attack in town.
The 16-year-old was standing at the bus stop near the Penny Whistle pub in Abington Square when she was approached by a group of teenage boys, one of whom appeared to film her with his mobile phone while being verbally abusive towards her.
The girl ran after the boy down a nearby alleyway while he continued to record.
She was then held by another boy while the suspect punched her in the face using a knuckle duster. A third boy spat at the victim.
The incident happened between 4.30pm and 4.50pm on Saturday, 13 June, although Northamptonshire Police have only just released the information to the media.
The boy who held the victim is described as black, about 14-years-old and was wearing tracksuit style clothing. The boy who spat at the victim is described as mixed-race, about 14-years-old and was also wearing tracksuit type clothing.
There were a number of people around the bus stop at the time of the incident and police are appealing for witnesses, or anyone with information, to call Northamptonshire Police on 101.
