A MURDER investigation has been launched after a man who was struck by a car on a seafront road died from his injuries.

The 20-year-old from Crawley, who suffered serious head injuries in the incident, died in hospital tonight after the hit-and-run on Sunday morning.

The Crawley man, along with two other men, were hit by a car in Marine Parade after a large fight broke out on the road at 5.20am.

The two other victims, an 18-year-old man and a 22-year-old man, who were also injured, remain in a serious condition in hospital.

A 32-year-old man who was arrested on Sunday on suspicion of causing grievous bodily harm has now been released under investigation. 

A 33-year-old man who was detained on suspicion of attempted murder this morning remains in custody.

The vehicle, a BMW X6, was later found abandoned nearby.

Detective Chief Inspector Chris Friday of the Surrey and Sussex Major Crime Team: "Our thoughts are with the family and friends of the victim who has sadly died this evening and with those of the other two victims who are in serious condition in hospital.

"This is now a murder investigation and we are again appealing for anyone who may have seen the incident or has any information about it to come forward.

"We are particularly keen to hear from anyone who may have mobile phone footage, dashcam footage or anyone with private CCTV footage of the incident.

"Marine Parade is likely to remain closed between the pier roundabout and Camelford Street until tomorrow afternoon while we are continuing searches and carrying out enquiries and I would like to thank the public for their patience."

Sussex Police said the incident is not terror-related.
