Diners ran for safety - staff closing the doors behind them - after mourning Mongrel Mob members launched a vicious attack on two people outside a central Palmerston North cafe on Thursday afternoon.
CCTV footage showed one woman scooping a small child into her arms and running into The Coffee Club The Square as at least six people wearing Mongrel Mob insignia and colours began attacking two other people.
Footage showed just how ferocious the incident was, with the two people knocked to the ground and then repeatedly kicked, punched, dragged and stomped on.
Some of the attackers even used cafe chairs as weapons, repeatedly bringing them down on the pair. A motorcycle was also driven onto the footpath behind the fracas at one point.
The incident unfolded when gang members in a funeral procession for Raniel Kiu - whose death last week police are investigating as a homicide - jumped from a vehicle as it passed through Main St, near The Square, and allegedly attacked two men with facial tattoos who were on the footpath, Stuff reported.
