Girl posts birthday party on facebook. What could possibly go wrong?

This is probably one of the craziest stories I have ever come across. A girl living in a small town called Haren in the Netherlands posted a party invitation on facebook to celebrate her 16th birthday party. She didn't set the event to "private" and the invitation went viral. The invitation was passed onto about 30,000 people. Thousands of people showed up ending in rioting, injury and damage to property. Riot police broke up crowds who flocked to the town. The girl who issued the invitation fled her home in Haren, a town of just under 19,000 on Friday.
