Police are appealing for witnesses after a two-car collision in Northumberland on Saturday.
It happened at 12.10pm, approximately half-a-mile north of New Moor House crossroads. A Mercedes car was travelling south and a Land Rover was travelling north when, for reasons yet to be established, they collided.
A passenger in the Mercedes, a 20-year-old woman, sustained serious injuries and was airlifted by the Great North Air Ambulance to the RVI in Newcastle, where she is still receiving treatment.
She arrived after a 12-minute flight in a stable condition, but with multiple serious injuries.
The road was closed for approximately four hours while the casualty was dealt with, the vehicles recovered and the scene examined by police.
Anyone with information is asked to call 101, quoting reference 549 of 30/09/17.
