A 31-year-old man has been arrested after a woman with serious injuries was found next to a burning car on a dual carriageway and died at the scene.
Officers were called to the car fire on the southbound side of the A21 near the exit for Tonbridge, Kent, at 2.34am.
Paramedics attended but pronounced the woman dead at the scene. Two fire engines also rushed to the roadside to extinguish the blaze.
Kent Police said a 31-year-old man in London has been arrested and officers are 'working to establish the full circumstances'.
The A21 remains closed in both directions between Morley's roundabout and Tonbridge bypass while detectives hunt for clues. A drone has also been sent into the sky to scour the surrounding area.
