A group of girls ended up in hospital after being attacked by another teenager in Bristol.

They were assaulted in the fields near Pomphrey Hill, Mangotsfield, behind Cleve Rugby Club.

Avon and Somerset police spokeswoman Catherine Foster said: "A few girls in the group left the location but were then assaulted by a number of youths.

"They all received injuries that required hospital treatment.

"Police are now hoping to speak to a white female, around 15 to 17 years old, who may hold information which could help with their enquiries."
