Nikola "Niko" Hećimović, also Nicholas Hećimovića (26 November 1900 – 25 April 1929) was a Croatian communist organizer and secretary of the Yugoslav branch of International Red Aid.
He was arrested on 20 April 1929 and after several days of intense questioning by police[2] he and Đuro Đaković allegedly escaped and attempted to flee to Austria.
[4][5] Đaković and Hećimović were shot on 25 April in the Šele Ravine (Slovene: Šelova graba) in the hamlet of Šelovo in the northern part of the village of Veliki Boč.
The 1976 film Četiri dana do smrti (Four days until death) by Miroslav Jokic features the arrest and execution of Đaković and Hećimović.
In 1979 the Yugoslav Post issued a stamp commemorating fifty years since the assassination of Đaković and Hećimović.
