Another Ustaše terrorist organization, the Croatian Revolutionary Cell, Bruno Busic Department, bombed the R. S. Schullz publishing house in Percha on Lake Starnberg, Germany, on August 19, 1981. The group, which claims to be based in Paris, used one kilogram of Swiss Mark 2 dynamite. They threatened to use two more kilograms the following week if the firm published Tito's memoirs.
