Much of what police are calling a "violent disorder" happened on the A413, with passing traffic narrowly missing people in the road.

Thames Valley Police say this was a "serious" incident, but fortunately no one was badly hurt.

A spokesman for Thames Valley Police said: “This was an unacceptable outbreak of violent disorder where a number of people were attacked in what appears to have been a pre-meditated and orchestrated incident.
