An underage party in Oamaru ended with an arrest and a damaged house.
Acting Sergeant Larissa Berends said police arrived at the out-of-control youth party at 10pm on Saturday.
The youths were drinking and the house was "moderately damaged".
A 16-year-old male was arrested for possession of an offensive weapon.
It was not the only youth crime to hit Oamaru last week.
At 10am on Friday a 17-year-old male was arrested for causing willful damage to a Labour campaign billboard.
He was referred to youth aid.
