Officers are investigating a suspected road traffic collision on the M1, where a man has sadly died.
The man’s body was found by police close to the hard shoulder of the M1 motorway between Junctions 4 and 5 on the northbound carriageway at around 2.30pm on Monday, December 4.
It is suspected that he was struck by a vehicle which did not stop, sometime between 4.30am on Sunday, December 3, and 2.30pm on Monday, December 4.
The road was closed whilst investigations took place and it was reopened at around 8.30pm the same day.
Detective Inspector Garry Webb, from the Bedfordshire, Cambridgeshire and Hertfordshire Road Policing Unit, said: “Our thoughts are with the man’s family at this terrible time. Specially trained officers are supporting their family.
“We want to hear from anybody who saw what happened or has information that can help. If you were driving along the M1 and have a dashcam, please check it and get in touch if you spot something that might help our investigation.
“We believe a number of cars stopped when the collision occurred and we are particularly keen to hear from the driver of a white Mercedes.
“Finally, I would like to thank the public for their patience whilst we carried out investigations at the scene yesterday. We appreciate the road closure would have caused disruption.
“If you can help, please get in touch by emailing the team on SCIUSouth@bch.police.uk quoting Op Byron.”
