A 20-year-old man is fighting for his life following a crash between two Seat Ibizas in the Scottish Borders.
The incident happened on the A7, around half-a-mile north of Galashiels, shortly after 9pm on Monday.
Police said a red Ibiza was travelling south when it collided with a black Ibiza on its way north on the other side of the carriageway.
Emergency services attended and the 20-year-old male driver of the red car was taken to hospital, where medical staff have described his condition as critical.
The driver of the black car was examined by ambulance staff at the scene and did not require hospital treatment.
The A7 was closed for several hours for investigation works.
Sergeant Jill Kirkpatrick said: “Enquiries carried out so far have established that another black car, make currently unknown, was in front of the red Seat prior to the collision and I would ask the driver of that vehicle to contact us as they may have information which could assist our enquiries.
“I would appeal to anyone who was on the A7 around the time of the incident to contact us with any information or dashcam footage as it could prove vital in our investigation.”
If you have any information, call 101.
