A woman who sustained serious injuries in a hit and run on the Melrose bypass remains in a critical condition in hospital as police continue to hunt for the driver.
Drivers with dashcam footage of the collision, which occurred on March 12 on the A6091, are urged to contact officers.
A 60-year-old woman was hit by a car which failed to stop near to the Borders General Hospital around 9.50pm.
An investigation is ongoing and officers are keen to speak to anyone who saw a dark-coloured SUV and a 4×4 at the time of the crash.
The drivers of these cars have been urged to come forward with information.
The drivers of a silver Ford Fiesta, a red hatchback and a small white hatchback have already come forward and police say they have been eliminated from enquiries.
Chief inspector Vinnie Fisher, local area commander, said: “I would like to thank everyone who has come forward so far and spoken to officers. Thanks to them we have managed to eliminate a number of vehicles from our investigation.
“But it is vital that we do trace those involved. A woman has been seriously injured and she and her family deserve to know what has happened.
“Officers held a road check at the location of the crash on Sunday, March 19, a week on from the crash and again I want to say thank you to everyone who spoke to us and passed on information.
“An examination of CCTV shows there are a number of vehicles driving in the area at the time whose owners or drivers have not yet come forward and I am urging them to do so.
“You may be unaware of having been involved in the crash, but if you were there is likely to be damage to your vehicle.
“I cannot stress enough how important it is that if you were driving in the area around 9.50pm on Sunday, March 12, 2023, you check your car now and speak to us even if it is to report no damage.
“The more vehicles we can eliminate from our enquiries the closer we come to finding out what happened. Please, if you have not yet come forward then make contact with us now.
“Anyone with information is asked to call Police Scotland on 101, quoting incident number 3302 of Sunday, March 12, 2023.”
