Police faces protesters and spectators during the official visit of the Shah in the Rathaus Schöneberg in Berlin. Rathaus Schöneberg served as the seat of the city senate and office for the Mayor Heinrich Albertz. On June 2, 1967 Pahlavi was received in West Berlin, accompanied by violent clashes of protesters with Iranian secret police collaborators and massive police forces, whereby the student Benno Ohnesorg was shot by police officer Karl-Heinz Kurras, an incident that became a turning point in the devolution of the German student movement. On 26 September Mayor Albertz was forced to resign after an investigation into the police's role in the killing.
