A Romanian man and woman have been named as those killed in a crash a couple of miles south of the Carter Bar earlier this month.
Ionel and Christina Minerva Rostas, 26 and 31, were pronounced dead at the scene of the two-car collision near Byrness on Wednesday, April 17.
Another man was airlifted to hospital in Newcastle with serious injuries.
Investigating officers from Northumbria Police are keen to speak to the driver of a dark coloured vehicle which drove around the collision scene shortly after it happened.
Police believe this witness could hold information which will assist the investigation. Anyone with any information should contact 01661 872555.
