Police are keen to hear from anyone who may have information after hundreds of young people wreaked havoc in Mosigel.

A party that was originally made up of 20 teenage guests was shutdown at around 11 on Saturday night, after numbers swelled to around 200.

The youths moved into the streets and Memorial Park, where police say they began to yell, fight, and smash bottles.

Two were arrested, while the rest of the crowd left when a police van arrived from Dunedin.
