A teenage boy has been arrested after a police officer was assaulted in a city centre.

Police were called to St George's Street in Canterbury at about 4.30pm yesterday, after a report of a group of young people causing a nuisance near the city centre's McDonald's.

While speaking to those at the scene, a male officer was assaulted.

A knife was later recovered nearby, and a 15-year-old boy was arrested on suspicion of assaulting an emergency worker and possession of a knife.

He has since been bailed, pending further enquiries.

The officer is not believed to have been seriously injured in the assault.

A 13-year-old boy was also arrested on suspicion of criminal damage, in relation to a pair of glasses belonging to a bystander that were damaged.

He has since been released without charge.

Photos taken yesterday evening showed two patrol cars and a police van parked up near McDonald's in Canterbury high street, while the incident was being dealt with.
