Sergeant Simon Cooper, of the Bedfordshire, Cambridgeshire and Hertfordshire Road Policing Unit, said: “Despite the best efforts of the emergency services, a man sadly passed
away at the scene.
"We have informed his next of kin, and they are currently being supported by specially trained officers. We ask that their privacy is respected at this difficult time.
“We are appealing for the public’s help so we can give them some answers. If you were driving in the area at the time, did you witness the collision or the events leading up to it?
"If you do have information and haven’t already spoken to us, please get in contact as a matter of urgency.
“If you were in the area and have a dash cam fitted to your vehicle, we ask that you please review the footage and send us anything you think could assist with our investigation.”
