A NSW man has been charged with manslaughter after a road-rage incident that left another driver dead.

Emergency services were called to Jersey Road at Blackett, in Sydney’s west, on Thursday morning after reports that a pedestrian had been hit by a car.

The 27-year-old man, who was wearing high-visibility clothes and had been named in multiple media reports as tradie Rhyce Harding, died at the scene while being treated by paramedics.

Police have said they believe he was hit by another vehicle and likely dragged along the road for about 100 metres before ending up on the ground.

The other driver left the area.

On Friday, a 39-year-old man went to Mount Druitt police station and was subsequently arrested. NSW Police said on Friday afternoon that he had been charged with manslaughter, failing to stop and assist after vehicle impact causing death, negligent driving (occasioning death), and dangerous driving occasioning death – drive manner dangerous.

He was refused bail and will appear in Parramatta Local Court on Saturday.

Police also said that “following extensive inquiries”, they had seized a white Toyota Hilux was seized on Mileham Street, Windsor. It will undergo forensic examination.

On Thursday, Acting Inspector Shane Ranee said the incident likely followed a road-rage confrontation.

“We have information that the same car hit the victim,” Ranee said.

“Apparently the victim had gotten out of the vehicle after being threatened by the car following him.

“Words were said, that’s what led us to believe it could have happened because of a road rage incident.”

Police said they believed Harding might have been dragged by the ute, which fled the scene.

“It’s devastating. I feel bad for the victim’s parents and the victim’s family,” Ranee said.

Police said earlier they did not know if Harding and the other driver knew each other before the incident.
