Woman 'hit by cars' and killed on road near Oxford
Police believe a woman may have been struck by a number of cars before dying in a collision near Oxford.
The 21-year-old, from Cheltenham, Gloucestershire was hit by a Ford Ka at about 22:30 GMT on Monday.
She was pronounced dead at the scene on the Oxford-bound carriageway of the A40, between Forest Hill and Thornhill park-and-ride.
Thames Valley Police is hoping to speak to drivers who were in the area before the collision.
PC James Mahony said: "We would like to speak to anyone who did not stop in the area at the time of the collision, but who thinks they may have struck something in the carriageway at around that time and place.
"They may not have been aware that it was a person."
The woman's next of kin have been informed.
