Mitch Voysey, 17, was struck by a car when he was allegedly chased onto Lake Rd by a group of attackers on Friday night.

He suffered critical injuries and was raced to Newcastle’s John Hunter Hospital.

The teenager, an apprentice butcher, died on Saturday night.

Another victim suffered serious head injuries when he was allegedly king hit by an attacker and knocked unconscious.

The 20-year-old man was airlifted to St George Hospital in Sydney.

It is understood he is now in a stable condition. Police have not released his name.

Three Port Macquarie men and a 17-year-old youth from Herons Creek have been arrested and charged with manslaughter.

The first man to be arrested, 27-year-old Wayne Galbraith, was charged with assault in company occasioning grievous bodily harm and affray, in relation to the king hit.

The manslaughter charge was added yesterday.

Police said the deadly assault occurred when the four men, who were driving a red Toyota Corolla, allegedly confronted the victims and two of their friends at Lake Rd, east of Jindalee Rd, at 11.35pm.

The driver of the car stopped the car near the group and an altercation took place.

During the fight, three of the attackers allegedly chased Mr Voysey across the road and he was struck by a white Subaru Outback driven by a 29-year-old Port Macquarie man.

Port Macquarie detectives, Crash Investigation Unit officers and emergency services personnel attended the scene.

Police seized the accused men’s car as well as the other vehicle involved.

Inspector John Sullivan of the Port Macquarie police said the four men who were arrested “have been charged with manslaughter and other offences relating to the death of the Port Macquarie youth and the assault of another Port Macquarie man”.

The accused have been refused bail and will appear before Port Macquarie Local Court today and Port Macquarie Children’s Court today, Insp Sullivan said.

Police urge anyone with information to contact Port Macquarie police or Crime Stoppers on 1800 333 000.
