The girl's parents had given permission for the party, to which 75 people had been invited via the internet. But the party proved a little too successful, as around 200 people are thought to have descended on the house, according to the police.
Having celebrated the New Year elsewhere, the parents returned in the morning to find footprints on the walls, banisters damaged, and the mother's wardrobe floating in the swimming pool outside.
Several vases, sculptures and three laptops were also stolen during the party, and youths had apparently urinated in various parts of the house. The cleaning bill was estimated to run into several thousand euros.
The parents have pressed charges, though it is unclear against whom.
