A man was left with a fractured jaw after being attacked by a group of men in Barrowford.
It happened on Sunday 14 October at some time between 4:30pm and 6pm close to the edge of Victoria Park on Carr Road.
The victim, a 19 year old Nelson man, had attended the park with a friend. They have been confronted by a group of around 30 to 35 men and the victim was hit repeatedly with knuckledusters, causing him facial injuries which required surgery.
DC Hazel Richardson from East CID said: “This young man was assaulted after trying to pull his friend back as he was being dragged by some members of this gang.
“This was a particularly large group of Asian men and so someone must have seen something. If you know anything that you think could help, please get in touch with us.”
