Police conducted dawn raids across Germany on Tuesday as part of investigations into violent clashes between anti-capitalist protesters and officers in Hamburg at the Group of 20 leaders’ summit in July. Officers were searching properties of the anti-capitalist group known as the ‘Black Bloc’ in several federal states, Reuters reports. Scuffles between police and some anti-capitalist militants marred the G20 summit. The raids involved some 20 properties in seven states, including Hamburg, Berlin, North Rhine-Westphalia and Baden-Wuerttemberg, and officers had seized data and communications equipment, according to Spiegel.
