Infuriated by Heydrich's death, Hitler ordered the arrest and execution of 10,000 randomly selected Czechs. But after consultations with Karl Hermann Frank, he altered his response. The Czech lands were an important industrial zone for the German military, and indiscriminate killing could reduce the region's productivity. Hitler ordered a quick investigation. Intelligence falsely linked the assassins to the towns of Lidice and Ležáky. A Gestapo report stated that Lidice, north-west of Prague, was suspected as the assailants' hiding place because several Czech army officers, then in England, had come from there and the Gestapo found a resistance radio transmitter in Ležáky. On 9 June, after discussions with Himmler and Karl Hermann Frank, Hitler ordered brutal reprisals. Beginning on 10 June, all males over the age of 16 in the villages of Lidice and Ležáky were murdered. All the women in Ležáky were also murdered.
