Police want to trace a man who disappeared from the scene of a crash in which another man received serious head injuries.

The accident happened in Jubilee Way, Didcot, at the junction with Hagbourne Road, shortly before 1am on Sunday, when a G-registered, gold-coloured Vauxhall Cavalier veered off the road.

Thames Valley Police said a 27-year-old man in the car was taken to the John Radcliffe Hospital, Oxford, with serious head injuries.

Police are still trying to trace a second man in the car.
