A man has been killed crossing the A5 - just moments after surviving a car crash.
The 30-year-old driver was hit by a Toyota Rav 4 on the dual carriageway on Friday night.
He had just got out of his blue Volkswagen Polo after it had overturned on the Caldecotte roundabout.
He was taken to John Radcliffe Hospital, but later died of his injuries.
The driver of the Toyota called for help at the scene, police say.
If you witnessed the collision or have any information to help investigators, call Det Sgt Gavin Collier on 101 quoting URN 1759 11/12.
