During the 2017 G20 summit, which took place in Hamburg from 7–8 July that year, protestors clashed violently with the police in the Sternschanze area and particularly around the Rote Flora. On 7 July, several cars were set on fire and street barricades were erected to prevent the police from entering the area. In response to that, the police made heavy use of water cannons and tear gas in order to scatter the protestors. However, this was met with strong resistance by protestors, resulting in a total of 160 injured police and 75 arrested participants in the protests.
