TWO teenage boys are fighting for their lives after a serious crash near Wallingford.

Thames Valley Police said two 16-year-old boys are in a critical condition with 'life-threatening' head injuries, following the crash in Ewelme.

It is understood that one of the boys was driving, after police confirmed all four people in the car were 16. 

They were injured when a green Vauxhall Corsa smashed into a tree and hurtled to a stop in a field near Days Lane, near the Beggarsbush Hill junction, at about 11.10pm on Saturday.

Police said two other 16-year-old boys suffered less serious injuries, including one who broke a collar bone. 

He confirmed the two who were seriously injured, who remain at the John Radcliffe Hospital, were rear-seat passengers.

The other two teenagers were also taken to hospital, but have since been discharged.

Police have made no arrests.

Senior investigating officer Sergeant Chris Ruff, of the Joint Operations Unit for Roads Policing in Abingdon, said: "This is a very serious collision which occurred in a rural location, which sadly has left two boys with life-threatening injuries.

"I am appealing to anyone who may have seen the incident, or witnessed the vehicle being driven just prior to the collision, to make contact with us."

Anybody who witnessed the collision or has any information has been urged to contact 101, quoting URN 1530 (12/5), or contact Crimestoppers anonymously.
