The German penal-investigation camp in Żabikowo near Poznań was established in April 1943. Until the spring of 1944, it functioned in parallel with the camp in Fort VII in Poznań, of which it was a continuation. At the time of the liquidation of the camp, on April 27, 1944, there were 750 prisoners in Fort VII. Commandant Reinhold Hans Walter and the entire crew, numbering from 80 to 100 SS men, moved to Żabików.
The camp in Żabikowo was officially named Polizeigefängnis der Sicherhaitspolizei und Arbeitserziehungslager Posen-Lenzingen (Security Police Prison and Educational Labor Camp Poznań-Junikowo). The camp was divided into two parts, a police prison and a penal camp. The Żabików camp, with an area of approx. 3.74 ha, was subordinated to the Poznań Gestapo and was organized on the site of a former brickyard. It was surrounded by a double high-voltage barbed-wire fence and guard towers. Thick coils of barbed wire were additionally placed between the wires to prevent escape. There were separate barracks for men and women in the camp, the conditions of stay did not differ from those in concentration camps. The Security Police prison was a temporary place of isolation where people accused by the Germans of conspiracy activities were sent. The period of imprisonment of a prisoner lasted on average from several days to several weeks.
However, there were cases in which individual prisoners stayed here for several months. Prisoners were kept in wooden barracks (some of these barracks remained after the liquidation of the existing labor camp for Jews - Reichsautobahnlager Poggenburg). The camp in Żabikowo was a transit camp, from where prisoners were deported to concentration camps and occasionally released. 28 transports with prisoners left Żabików. The first transport was sent to KL Auschwitz, and then to Gross-Rossen, Mauthausen, Sachsenhausen, and Ravensbrück.
