Warsaw, 24 June 1946. Investigating Judge Halina Wereńko, delegated to the Commission for the Investigation of German Crimes, interviewed the person specified below as a witness.

My nephew Wojciech Całczyński (19 years old) was arrested by the Germans in 1942 or 1943, transported to the Gestapo HQ on aleja Szucha, from where, after an interrogation that included beating, he was sent to Pawiak prison for a few days; he was then sent to the prison on Gęsia Street, where he stayed for a few weeks. He was lucky to be released with the help of a detective friend of his, who worked for the 7th Police Station of the state police. Currently, my nephew studies at the school of irrigation in Otwock Wielki, Warsawcounty, the estate of count Jezierski. I pledge to inform my nephew, as soon as he arrives in Warsaw, that he should visit the District Commission for the Investigation of German Crimes in order to testify.
After he had been released from prison on Gęsia Street, my nephew was arrested for the second time and kept in the camp in Zaborów near Warsaw, where he was beaten cruelly. Eventually, he was released.
After the Uprising was over my nephew was transported away by the Germans to a concentration camp; I do not remember the name.
