On 15 July 1942 Löwy was arrested by the Gestapo at ten in the morning. The arrest came in the wake of an arson attack on an exhibition held between 8 May and 21 June 1942 in Berlin's Lustgarten. Germany's Nazi government was not completely without its own somewhat ponderous sense of fun, and the goal of the ironically named Soviet Paradise exhibition, which according to official statistics, was visited by 1.3 million people, was to show "poverty, misery, depravity and need" of the nations in the Soviet Union under Jewish-bolshevik rule and thus to justify the war against the Soviet Union. The arson attack itself took place on 18 May 1942 and reportedly did little damage to the exhibition, but after some months it had been used to justify to the arrest of a relatively large number individuals, identified as members of the "Baum-Group". Of those arrested, at least 33 would be executed. There is no suggestion that Hildegard Löwy herself had not been involved in the arson attack on the exhibition in the park. She was one of the first to be arrested, was taken to the at Berlin-Moabit.
