SA units stormed the Social Democrats' headquarters in Königsberg, destroying the premises and even beating Communist Reichstag deputy Walter Schütz to death.[11] Other non-Nazi party officials were attacked by the SA in Wuppertal, Cologne, Braunschweig, Chemnitz, and elsewhere throughout Germany, in a series of violent acts which continued to escalate through the summer of 1933; meanwhile the SA's membership grew to some two-million members.[12]
