One young Dutch girl might never want to throw a party again. A 16th-birthday party invite on Facebook that wasn’t marked as private ended up being spread to 30,000 people in the Netherlands. In the end, 3,000 partiers showed up to the town of Haren (population 19,000) on Friday despite the party being canceled and police warnings. Six hundred riot police blocked off the girl’s street, but that didn’t stop revelers from looting shops, setting a car on fire, and attacking officers with bottles and rocks. Twenty arrests were made and at least six were injured.
