The Supreme People's Court said on Wednesday that the case involving the country's former security chief, Zhou Yongkang, has not yet entered legal proceedings.

The court's spokesman, Sun Jungong, said information on the case has not yet been passed to the top court, adding that the investigation is still ongoing.

The central government announced on July 29 that it had launched a corruption investigation into Zhou, a former member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee, saying he is being probed for "serious disciplinary violations".
