Bottles were hurled at police by "idiots'' as they responded to disorder in Dunedin's student quarter at the weekend.
Police were initially called to a noise complaint in Castle St at 9.30pm on Saturday, Senior Sergeant Craig Dinnissen said.
They found general disorder and students breaking glass.
Later that evening, they were called to a couch fire in Castle St, where "idiot'' students threw bottles at officers, he said.
No officers were injured.
