In March 2006, Osaka police raided six facilities, including the North Korean Chamber of Commerce, in an investigation into the circumstances surrounding the June 1980 disappearance of one of the alleged abductees, Tadaaki Hara. All six facilities were linked to Chongryon, a pro-Pyongyang Korean residents' organization in Japan. A police spokesman said that the head of Chongryon at the time was suspected of cooperating in his abduction.[19]
