Officers searching for missing woman, Barbara Colling, are appealing for a vital witness to come forward.
The man was driving a dark blue estate car south along the B1257 close to Newgate Bank, on Monday January 28th.
A witness told police that they believe the man driving the car exchanged waves with a woman believed to be Barbara as she walked along the road.

I ask them to contact North Yorkshire Police on 101, select option 1 and pass the information to the Force Control Room.”
Anyone who can help locate Barbara Colling is urged to contact North Yorkshire Police immediately by dialling 101, selecting option 1 and passing the information to the Force Control Room.
The family of Barbara Colling have thanked members of the public for their help in trying to find her.
