A woman who was found dead on the M20 has been named as Dominique Worrall.
The 32-year-old's body was discovered by police on the London-bound carriageway near Ashford at 6.05pm on Tuesday.
A man who was arrested on suspicion of murder after officers appealed for the driver of a silver Nissan Qashqai to come forward has been released on bail, Kent Police said.
The circumstances surrounding Ms Worrall's death remain a mystery and detectives are continuing to investigate.
Police are still appealing for drivers who were on the road at the time to check their vehicles for signs of a collision, and for anyone with dash cam footage or who saw a Nissan Qashqai with the registration KY15 WWX at the time of the incident to come forward.
