On the 24th of June, 2014 the district of Friedrichshain-Kreuzberg made an operation called "voluntary moving". The idea was to empty the former Gerhart-Hauptmann school, occupied by refugees since December 2012. The procedure involved over 1000 police officers and blocked the complete neighbourhood. From the 300 of the school's inhabitants, around 40 people didn't accept to leave. Instead they stayed inside and resisted for 9 days on the roof of the building.
