We are appealing for information after a teenager was attacked by a man in Lancaster.
Sometime between 1.30pm and 1.40pm on Sunday (October 16), the victim, a 13-year-old boy, was cycling on Lune Street towards the Millennium Bridge.
As he continued across the bridge he fell from his bike and shouted an expletive.
While stood by his bike, a man walking with a young girl approached the teenager and grabbed him by the throat, telling him not to swear.
The suspect then walked off towards the St Georges Quay area. He is described as in his early 40s and has short dark hair. He was wearing a navy blue jacket. The young girl appeared to be under 10-years-old.
A member of the public witnessed the incident and helped the victim before calling police.
Police are appealing for witnesses and are asking anyone who can assist with their enquiries to come forward.
PC Adam Jussub, of Lancashire Police, said: “This assault was an unprovoked attack on a 13-year-old boy.
“The suspect was with a young girl and the fact she was a witness to this violent attack is quite worrying.
“From CCTV enquiries there appear to be several people walking around on the bridge at the time of the incident and we believe would have seen the offender.
“If you recognise the man described or saw the assault, please get in touch with police.”
Anyone with information can contact police on 101 quoting crime reference WB1608422.
