Police are on the hunt for a vehicle following a fatal collision in Bradford.
They would like to speak to the occupants of what is thought to be a Ford vehicle, which was travelling along the A641 Huddersfield Road at about 8.30pm on 24 February, when it was overtaken by a silver Vauxhall Astra which was involved in the collision a short time later.
Jane Floweth, who was 68 and from Ilkley, was a passenger in a blue Honda Jazz, which collided with the Astra on Common Lane, near the Guide Post Hotel.
She was taken to hospital where she later died from her injuries.
A 24-year-old man has been arrested on suspicion of causing death by dangerous driving and remains on bail pending further enquiries.
