The Central Arrest in the Warsaw ghetto

The Central Arrest in the Warsaw Ghetto, officially the Central Arrest for the Jewish Residential District (Zentralarrest für den jüdischen Wohnbezirk), commonly referred to as Gęsiówka, was a prison facility in the Warsaw Ghetto during World War II. It operated from 1941 to 1942. The detention center was located on the site of a pre-war Polish military prison at Gęsia Street. It was formally subordinate to the Polish Police of the General Government ("Blue Police"), while its staff consisted of members of the Jewish Ghetto Police. The facility detained Jews accused of offences against German occupation regulations. In spring 1942, approximately 190 Roma and Sinti individuals were also held there. The prisoner population grew steadily, reaching around 1,800 by July 1942. Living and sanitary conditions were extremely poor, leading to high mortality. Executions took place on the premises, including two recorded in November and December 1941 involving Jews caught on the "Aryan side" without permits. Other prisoners were executed at separate locations. During Grossaktion Warsaw in summer 1942, the inmates of the Central Arrest were among the first groups deported to the Treblinka extermination camp.
