Two dozen top officials investigated

Supreme People's Procuratorate continues probes during national anti-graft campaign

National prosecuting departments investigated 24 high-ranking officials from January to November last year, including former security chief Zhou Yongkang and former vice-chairman of the Central Military Commission Xu Caihou, for alleged graft, according to the Supreme People's Procuratorate on Thursday.

"The SPP is conducting direct investigations into four of them, including Zhou Yongkang," a senior official at the SPP said, adding that they will assign other provincial-level prosecuting departments to handle the other 20 officials.
