A dozen people were arrested and a man smashed an ambulance window, covering a paramedic in glass, at a Dunedin street party tonight.
Some 4,000 tickets were sold for the Hyde St keg party, an annual student blow-out known for its excessive alcohol consumption.
In a statement released about 8.30pm, police said a dozen people had already been arrested for offences including assault on security staff, fighting, disorder and offensive behaviour.
A particularly distressing incident involved an intoxicated male who damaged three vehicles including shoulder-barging the windscreen of a St Johns ambulance. The female paramedic inside was covered in shattered glass fragments.
"This is yet another example of the harm alcohol causes and the poor decision-making of those under the influence," Inspector Mel Aitken said.
