OXFORD: Police are still investigating an assault at this year’s Headington Festival.

A 10-year-old boy claimed he was assaulted at the event in Bury Knowle Park after a group of about five children aged between 10-12 approached him at around 6.20pm on Sunday.

He was threatened before one boy hit him, then fled.

His face was swollen and he needed treatment at the John Radcliffe Hospital.
