Diambu, president of the local chapter of the Congolese Press Union (UPC) and a broadcaster with the private station Radio-télévision Matadi (RTM), was arrested in late November and detained at the Matadi National Information Agency (ANR) offices. Diambu appeared before the Kinshasa Military Court and was charged with breaching state security for hosting an RTM television program on which he allegedly interviewed representatives of the Congolese Rally for Democracy rebel forces.
