Ungdomshuset
A women's demonstration took place on 8 March, comprising more than 3 000 people. The police carried out systematic identity controls. In total, more than 750 people were arrested during the events (among them, about 140 foreigners). On 16 March, 2007, Danish police admitted to having mistakenly used a potentially lethal form of teargas. The gas, known as Ferret 40, was used against crowds during the riots following the demolition, although it is designed to penetrate doors and walls.
