On December 26, 1926, Na Seok-ju travelled south from Manchuria towards
Seoul. After using various disguises to get across the Chinese-Korean border and through different checkpoints, Na finally arrived in Seoul on December 28. He first went to the
Chôsen Industrial Bank, where he detonated a grenade near the loan department, destroying it. From there, he made his way to the Oriental Development Company building, where he shot multiple Japanese office workers within the building; Na then attempted to detonate another grenade in order to kill several higher-level employees, but failed when the grenade proved to be a dud. After leaving the second building, Na attempted to escape the premises, killing a Japanese police officer in the process. Na was pursued by the Japanese police force. In order to avoid being apprehended, Na Seok-ju shot himself three times in the chest, and died later that day after being rushed to hospital. ==Legacy==
