A 12-year-old boy who died in an accident on the A420 near Southmoor yesterday was on his bike, it has emerged.

The boy was from Southmoor and went to school locally, police have said.

It is understood he was cycling with a group along the Charney Road, between the junction for the Lamb and Flag pub and the A420 westbound at about 4.30pm, when the accident happened.

He was involved in a collision with a grey Honda CRV being driven towards Swindon.

An air ambulance and two other ambulances went to the scene and the boy was taken to the John Radcliffe Hospital with life-threatening injuries and was later pronounced dead.
