Police are appealing for a vital witness to come forward after a cyclist was seriously injured in a collision.

The cyclist, a 65-year-old local man, is currently “very poorly” in Airedale General Hospital near Keighley after he collided with a silver Renault van on Skipton Road, Embsay, at around 12.15pm on Thursday.

Investigating officers believe the driver of a small blue Mercedes car which overtook the cyclist just prior to the collision may have information.

Traffic constable Dave Clayton, of Skipton Road Policing Group, said: “The Mercedes had nothing to do with the collision but may be a vital witness.”

Anyone who can help is asked to call police on 101.
