Shortly after 6pm on Saturday 27 January, officers became aware of a vehicle of interest travelling southbound on the A23 near Pyecombe.
The Ford Focus failed to stop when required by police, and it was pursued onto the A27 eastbound, where it was involved in a minor collision between Falmer and Lewes.
The occupants decamped from the car but were quickly detained by officers on foot, assisted by the National Police Air Service helicopter.
A section of the road was closed in both directions as officers responded at the scene, and we thank the public for their patience and understanding.
