A man has died after a white BMW collided with a tree on a country lane and then caught fire.
Bedfordshire Police officers were called just after 18:30 BST on Wednesday to Shillington Road between Shillington and Lower Stondon.
The driver – a man in his 20s – was the only person in the BMW and was pronounced dead at the scene.
A man in his 50s, the owner of another vehicle, was arrested on suspicion of causing death by dangerous driving.
The victim's next of kin has been informed.
Sgt Tim Davies from the Bedfordshire, Cambridgeshire and Hertfordshire Roads Policing Unit, said: "This is a deeply tragic incident, and our sincere sympathies are with the friends and family of the man who died.
"We believe a number of vehicles may have passed in the opposite direction around the time of the collision, and are asking anyone who witnessed it or has any dashcam footage to please get in touch with us as a matter of urgency."
