A man who was seriously injured in a collision on the M23 at Crawley remains in a critical condition in hospital.
The 19-year-old man was airlifted to the Royal London Free Hospital, Whitechapel, after the collision in the northbound carriageway at 11.49am on Sunday (February 9).
A spokesman for Sussex Police said that, prior to the collision on the motorway, a vehicle the man had been travelling in had been briefly pursued in Moat Road, East Grinstead.
That vehicle had been allegedly taken without the owner’s consent.
It had also been involved in a collision with another car in London Road for which it had failed to stop at the scene.
The vehicle was then abandoned in Stace Way and two men ran from the car.
A 33-year-old man from Crawley was arrested nearby on suspicion of being carried in a vehicle taken without consent.
He has been released on bail until April 11.
The other man, from Crawley Down, was on foot when he was involved in a collision with a car driving northbound on the M23.
Police have referred the incident to the Independent Police Complaints Commission (IPCC) as a matter of standard policy because of the police activity at the time.
