In November 2001, police raided the Tokyo headquarters of Chongryon and its Tokyo regional office as part of an investigation into alleged embezzlement by one of it senior officials. This followed an arrest of Kang Young-kwan, 66, a member of Chongryon's central standing committee and a former head of its financial bureau, among other Chongryon officials, who admitted diverting $6.5 million on behalf of Chongryon from the Tokyo Chogin, a credit union set up to serve pro-North Korean residents which failed in 1999. About 400 Chongryon supporters scuffled with police after they gathered in protest at what they called an act of political suppression and racial discrimination.
