People started to feel that the police were taking sides with the city council and Faderhuset. Tensions boiled over when a demonstration on 24 September was attacked by the police. The reason for the police attack apparently was a bottle being thrown at a police van. The police responded with a full frontal baton-charge on the demonstration. This led to several hours of street fighting between police and demonstrators. During the street fighting, three hundred people were arrested, many of which had not been involved with the fighting. A lot of these later claimed to have been brutally treated while in police custody. This sparked anger amongst the supporters of Ungdomshuset and many stated that violent resistance was now not only necessary and justified but the only right course of action that they could choose.
