POLICE are appealing for witnesses after two cars crashed on the A19 at the weekend.

A Citroen Xsara and Vauxhall Corsa were involved in a head-on collision near Shipton by Beningborough, on the outskirts of York, on Sunday, just before 7pm. A couple from Stokesley were taken to hospital with serious injuries.

The drivers of both cars reported seeing an emergency services vehicle with its blue light flashing immediately before the collision.

A police spokesman said: "Our inquires suggest this was very likely a police van on its way to an incident, but inquiries continue and we are very keen to hear from witnesses."

Witnesses are asked to call police on (01723) 509555.
