On March 1, 2007, the biggest riots in recent Danish history broke out when the police moved in and evicted squatters in Ungdomshuset, which was followed by the demolition of the building. It is estimated that the eviction of Ungdomshuset and the damage done during the following riots has cost the city and the state around 100 million danish kroner (around 17 million USD). On September 1, 2007, additional rioting resulted from a protest marking six months after the demolition of Ungdomshuset.
