A 75-year-old driver from Hove has died following a suspected 'road rage' incident in Shoreham.
Emergency services were called to the A259 Brighton Road, just west of the Saltings roundabout around 4pm yesterday afternoon.
Earlier on, two vehicles had been involved in a minor crash near Brooklands Park on the A259. A silver Honda CR-V, driven by the man from Hove, had apparently clipped wing mirrors with a white Toyota Aygo driven by a 28-year-old man from Worthing. The driver of the Aygo followed the Honda towards Shoreham until both vehicles stopped and an argument is reported to have taken place.
Police are investigating to find out if the death of the 75-year-old driver was as a result of a medical episode or the actions of the other driver.
Detectives want to speak to anyone who witnessed the incident or what happened afterwards. They are particularly keen to hear from any other drivers who may have dashcam footage of the vehicles at any point between Worthing and Shoreham.
The road reopened shortly before 10pm.
A 28-year-old man from Worthing was arrested at the scene on suspicion of common assault and remains in custody.
