Four men have been arrested after a violent attack in central Auckland that left one person unconscious.
The ordeal started when a "large group of males" approached three people on High St in the Auckland CBD at 5:15am on Sunday.
Auckland City CIB Detective Senior Sergeant Scott Armstrong said one of the males has allegedly punched one of the victims in the head, knocking him to the ground unconscious.
"The other males in the group have then set upon the other victims stealing a number of personal items," he said.
Police responded quickly to the attack but the group of males had fled on foot towards Albert Park.
Officers found three offenders nearby, with a fourth offender located with assistance from a security guard, Armstrong said.
One person was transported to hospital with minor injuries but has since been released.
Armstrong said the behaviour displayed by this group of males was "violent and cowardly".
"We have no tolerance for this sort of behaviour against people who are just going about their business," he said.
"It is pleasing for Police that we have made these arrests and I hope this will bring some reassurance to the victims and our wider community."
He said support is also being provided to all victims and their families.
Four men, aged 18-19, will appear in Auckland District Court on Monday charged with aggravated robbery.
One person has been referred to Youth Aid Services and enquiries are continuing, Armstrong said.
