On 18 February 1943, the Scholls brought a suitcase full of leaflets to the university main building. They hurriedly dropped stacks of copies in the empty corridors for students to find when they left the lecture rooms. Leaving before the lectures had ended, the Scholls noticed that there were some left-over copies in the suitcase and decided to distribute them. Sophie flung the last remaining leaflets from the top floor down into the atrium. This spontaneous action was observed by the university maintenance man, Jakob Schmid. Hans and Sophie Scholl were taken into Gestapo custody. A draft of a seventh pamphlet, written by Christoph Probst, was found in the possession of Hans Scholl at the time of his arrest by the Gestapo. While Sophie Scholl got rid of incriminating evidence before being taken into custody, Hans did try to destroy the draft of the last leaflet by tearing it apart and trying to swallow it. However, the Gestapo recovered enough of it and were able to match the handwriting with other writings from Probst, which they found when they searched Hans's apartment.
