At the end of 2008, during the period of diffuse hostilities set off by the revolt in Greece after the police murder of Alexis, the Belgian Federal Prosecutor launched an investigation targeting anarchists and anti-authoritarians [1]. In 2010, on the basis of a list of actions attributed by the police to the “anarchist movement” and while the struggle against a new closed prison [2] in Steenokkerzeel pushed ahead, judge Isabelle Panou was assigned to the case, which was classified as anti-terrorism. In May and again in September 2013, upwards of ten searches were carried out as part of this investigation against various residences and the anarchist library Acrata, located in Brussels. It's only at this moment that the existence of an anti-terrorism investigation became visible for the first time. This investigation is led by the anti-terrorism section of the federal police, with support from National Security, the General Intelligence Services, and military security at different times, as well as by the anti-terrorism services of other European countries. The investigation was completed in 2014 and today sees twelve anarchists and anti-authoritarians sent to court.
