KEY POINTS:
Hastings police say they will guarantee the safety of any witnesses coming forward with information on recent unprovoked gang attacks in the city.
There have been three violent assaults in the past week, the latest in Flaxmere on Sunday night when a 21-year-old man was viciously beaten about the head and body when he opened his front door to four men.
The victim's partner grabbed her newborn baby and hid in a room to escape.
The offenders were wearing red and black and were believed to be affiliated to a local youth gang, she said. They had yelled out local youth gang slang during the beating.
Mongrel Mob members attacked a man on Friday while he was walking past a house in suburban Camberley and the previous Sunday a man was bashed at a birthday party in the same suburb.
Hastings police senior sergeant Stuart Fleming said the first two attacks were linked, but the most recent did not involve the Mongrel Mob.
He said members of the public, with information, should not be scared to come forward.
Police could not solve the cases without the public's help.
"Don't be scared to come to us, you're not going to get hurt talking to us," he said.
Mr Fleming said all the attacks were unprovoked.
He warned gang members, police would be cracking down on violent behaviour.
