An investigation is underway after a Rotorua bar patron was knocked unconscious and another kicked in the head as part of a violent, gang-led "unprovoked attack" overnight.
A group of gang members allegedly assaulted Rotorua Sports Bar patrons on Arawa St just before midnight.
Multiple people were injured, including two with serious injuries, police said.
A short time later a minivan full of more gang members arrived and they continued the brawl.
Innocent members of the public were "caught up" in the violence, police said.
