An AOS member supported the man's neck while others patched his bloodied head.
Southern District Command Centre shift commander Senior Sergeant Darryl Lennane said last night a 35-year-old Dunedin man in the vehicle, who was the victim of the earlier golf club assault, was charged with assaulting a female and wilful damage following a domestic incident.
He had been treated in Dunedin Hospital for a 3cm cut to his head and was being held in custody for an appearance in the Dunedin District Court this morning.
The other man in the vehicle was arrested on an unrelated cannabis charge.
It was unlikely other people would be charged as a result of the ''fracas''.
A witness to the earlier Cochrane St incident was shocked to see a fight spill out on the normally quiet street.
A man wearing all red and believed to have gang connections was ''hit by a golf club, and then I started calling police'', the witness said.
''He went down on the ground and they were kicking him and hitting him. I just saw heaps of blood from his head ... All I saw was blood.''
Another witness said she saw a firearm presented, but police now believe a firearm was not involved.
The street was cordoned off and several residents, including a women and two teenagers, escorted from the scene.
They were later spoken to by police.
One witness said there had been yelling and swearing coming from the property the day before the incident.
The Otago Boys' High School hostel in Melrose St was locked down about 3pm.
Snr Sgt Lennane said that was a precaution only as ''one of the persons involved in the fracas went to the hostel'' in an attempt to find a staff member he knew.
Police were also called to St Clair Beach following a possible sighting of the bloodied man in the area about 2.45pm.
A St John spokesman said paramedics treated a man in his 30s who had moderate head injuries.
