A woman has died almost a month after she was injured in a road crash.

The 33-year-old woman suffered serious injuries after her blue Hyundai Coupe SE left the road and crashed into a ditch at Stoke Lyne, north of Bicester, at 11.10pm on Wednesday, May 28.

Police said today she died on Friday.

Her name has not yet been released.

Sgt Bryan Smith, who is investigating the crash, said: "We are still keen to identify witnesses to the collision, which occurred in a very quiet area as previous appeals have proved unsuccessful.

"Because of the driver's death, it is now even more important we speak to anyone who saw the collision or this Hyundai in the moments leading up to the incident."

Anybody with information is asked to contact Sgt Smith on 08458 505505 or Crimestoppers on 0800 555111.
