Fischer took part in some street battles when the anarchist "Putzgruppe" attacked the police and hurt some officers a lot. (In German the word "Putz" can mean a cleaner, but in "Putz-group" it is an acronym. That means the letters stand for other words. "Proletarische Union für Terror und Zerstörung", i.e. "The Workers Union for Terror and Destruction").
