A man who was arrested on suspicion of murder after the body of a woman was found on the M20 has been released on bail.
The body was discovered by police on the London-bound carriageway near Ashford at 6.05pm on Tuesday. The road was closed between junctions 9 and 10 for nearly 24 hours while the scene was investigated.
Officers appealed for the driver of a silver Nissan Qashqai to come forward and a man handed himself in at a police station on Wednesday evening, Kent Police said.
On Friday morning the force said the man had been released on bail until March 15.
The circumstances surrounding the death of the 32-year-old from Kent remain a mystery and detectives are continuing to investigate.
A post-mortem is expected to take place at midday on Friday.
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.
