Over the course of June 17, 1953, paid criminal elements from West Berlin tried to incite the population of the democratic sector to commit violent crimes against democratic facilities, companies, stores, commercial buildings, and the People’s Police [Volkspolizei]. The West Berlin provocateurs roamed the streets, looting, robbing, and carrying out devious armed attacks on the People’s Police and progressive-minded segments of the population. For example, the ruffians destroyed consumer stands in the central market hall on Alexanderplatz and tore down overhead trolley lines at the Oberbaumbrücke. Bandits destroyed the interior of the Berolinahaus on Alexanderplatz. They forced their way into an HO [Handelsorganisation] food store on Liebknechtstraße and into other stores and kiosks. They not only stole goods but subjected store and kiosk employees to extremely brutal treatment. The bandits demolished the HO and Konsum kiosks at Ludwig Jahn Sports Park and set fire to the Columbushaus on Potsdamer Platz. They even attacked the hospital of the People’s Police, smashing windows in the women’s ward.
The population distanced itself from the provocateurs and their criminal acts, and assisted the People’s Police in arresting a large number of criminals, most of whom are West Berlin provocateurs from fascist organizations.
