A woman has suffered potentially life-threatening injuries in a crash in East Yorkshire involving what's believed to be a stolen car, police say.
It happened on the A63 near Welton at about 18:25 yesterday when a black Dacia Sandero was in collision with a silver MG ZT.
The MG is thought to have been stolen, police added.
A woman who was in the Dacia was left with potentially life-threatening injuries.
The 30-year-old driver of the MG suffered minor injuries and was arrested on suspicion of aggravated taking a vehicle without consent, driving while unfit through drink or drugs and dangerous driving.
Police are appealing for witnesses to the crash to come forward, especially people who may have seen the MG near the M18 just before the crash.
