On 17 November 2018, following the annual protest in commemoration of the student revolt against the military dictatorship in Athens, Greece, (1973), and despite the fact that this year's protest was ending in an absolutely peaceful manner, scores of riot policemen encircled the black block just before it was going to disperse and they suddenly launched a massive attack and charged against the crowd with batons while firing asphyxiating gas grenades and flash-bang grenades, creating chaos in a residential area of central Athens, just outside Ambelokipoi metro station.
