An out-of-control party at a student hot spot in Dunedin ended with four arrests of non-students, including one reveller so intoxicated he required constant police supervision.
The Fire Service was called to extinguish two couch fires at a large Castle St party late on Tuesday, which also attracted the attention of Campus Watch and police.
Acting Senior Sergeant Damion Rangitutia said four partygoers - aged 19-21 - were arrested just before midnight.
Two men and a woman were charged with disorderly behaviour likely to cause violence.
An intoxicated man, who was taken to Dunedin Central Police Station to sober up, was so drunk he required full-time monitoring by police, Acting Snr Sgt Rangitutia said.
Those arrested were likely to receive pre-charge warnings from police.
The occupants of the flat were also likely to face some form of disciplinary action from the University of Otago proctor, he said.
University of Otago student services director David Richardson confirmed those arrested were not from the University of Otago.
