Dunedin assault victim still in serious condition

The man who was assaulted at a Dunedin petrol station on Saturday night remains in hospital in a serious condition nearly two days after the incident.

A police spokeswoman said this afternoon the 43-year-old victim of an alleged assault by a gang member was ''in a serious but stable condition'' in Dunedin Hospital.

He was earlier reported to be in a critical condition.

The investigation is ongoing but it appeared police have yet to make an arrest in connection with the assault.

''Police are working to identify and speak to all persons present at the time of the incident,'' the spokeswoman said.

Meanwhile, a Dunedin man who helped the victim says his family are praying for the victim's survival.

Esitakio Moata'ane was driving along Hillside Rd about 10.30pm on Saturday when his daughter said: "Dad, there's a man lying on the ground in the Mobil."

He went to investigate and found a man unconscious outside Mobil Forbury with a severe head injury, struggling to breathe.

"He was drowning in his vomit ... so me and this other dude flipped him over and into the recovery position."

Mr Moata'ane said the man appeared to have been punched in the face before falling backwards and hitting his head on the ground.

"It was like a king-hit.

"There were no black eyes, it was just the mouth and the nose.

"He had an injury at the back of his head as well.

"He must have fallen back and smacked his head on the ground."

A deeply religious man, Mr Moata'ane said he stood and prayed for the victim before ambulance officers transported him to Dunedin Hospital.

He later asked his children to "pray for that man" before they went to sleep.

The 25-year-old forklift driver said his wife had given birth to their fourth child on Thursday, just two days before he and his children came across the aftermath of the vicious assault.

A woman who witnessed the incident told Mr Moata'ane one of a carload of gang members carried out the assault.

A gang member allegedly told the woman the victim had "got too lippy".

Detective Sergeant Nik Leigh, of Dunedin, said last night the victim was in a critical condition.

Police officers from the Criminal Investigation Branch (CIB) and forensic scientists from the Institute of Environmental Science and Research were at the scene yesterday.

The petrol station remained closed and cordoned off, with a scene guard stationed there overnight.

Det Sgt Leigh said police had not made any arrests in connection with the assault but were following positive leads.

"We've got some persons of interest we want to catch up with."

The CIB was yet to determine if it was "a chance encounter or something more", Det Sgt Leigh said.

Police were appealing for anyone who had information about the assault or who had been in the area on Saturday night, to contact them or provide information anonymously via the Crimestoppers line.
