At around 10.30am on Wednesday 8 August, a blue Vauxhall Corsa was involved in an incident on Dunstable Road, Caddington.

Det Constable Gail Cotton said: “We are continuing to investigate the circumstances surrounding this collision and would appeal for anyone who recognises the man pictured to come forward with information.
“I would also be keen to trace any witnesses to the collision itself, this is a busy road and we believe a number of cars passed at the scene.”
