A 16-year-old boy has been left with a broken jaw after being attacked by balaclava-wearing youths.

Between 7pm and 8pm on Saturday, April 13, the boy was in a field off Marlow Road, near to the Henley Rugby Club and River Thames.

He was with a group of friends when another group of approximately 20 people arrived.

The group then approached the victim and began to attack him, knocking him to the ground and kicking him in the head and body.

The group were all between the ages of 15 and 17 years old, with the majority wearing balaclavas or with hoods up.

The victim sustained a broken jaw and concussion and was taken to the John Radcliffe Hospital for treatment. He has since been discharged.

No arrests have been made.

Thames Valley Police are now appealing for witnesses of the incident.
