Partygoers pelt police
Police were pelted with bottles and other objects as they tried to shut down an out of control party.
Police were called to the house party in Sutherland Cres, Westbrook, about 10.20pm on Saturday following reports there were underage people drinking, bottles being thrown and the windscreen of a car parked in the street smashed.
As about 12 police converged on the property, they were fired upon with bottles and other missiles, Inspector Brett Calkin said.
Two officers were hit, but uninjured.
Five males and one female were arrested - three 16-year-olds, two 17-year-olds and a 19-year-old.
The 16-year-olds had been referred to youth aid, one 17-year-old was let off with a warning.
The remaining two will appear in the Palmerston North District Court on charges of assault, assault on police, and disorderly behaviour.
The people hosting the party, which had an adult present, co-operated with police.
It appeared that an invitation made to friends on Facebook had led to several gatecrashers arriving, Calkin said.
He advised people not to advertise their parties on social media, and that they register such gatherings with police.
