International Red Aid
Đaković actively opposed the January 6 Dictatorship of King Alexander I. Due to this, he was arrested in Zagreb together with Nikola Hećimović, secretary of the International Red Aid. They were executed on the Yugoslav-Austrian border on April 25, 1929. In an exaggerated attempt to escape responsibility, authorities have tried to conceal the murder. After exhumation, it was found that the victims were fired at a small distance, which proved to be a murder.
