The BMW driver also escaped unscathed.

Police are looking for a specific important witness and also want to hear from anyone who may have dash-cam footage.

Investigating officer, PC Kate Bishop, of the Serious Collision Investigation Unit, said: “I am appealing for witnesses to this tragic incident following which a woman aged in her nineties sadly died.

“I would appeal to any other motorists who were using the road in Longdown Hill in Cadsden at around this time on Monday, who may have seen this collision take place.

“Shortly following the collision, a man driving a dark coloured car stopped at the scene, but was no longer present on police arrival. We believe that this person could be an important witness and would like him to make contact with police.

“I would also ask that anyone with a dash-cam fitted to their vehicles reviews the footage in case anything significant was caught on it."
