Rumors about an investigation into Zhou Yongkang began swirling as early as April of last year because of his close association with disgraced politician Bo Xilai, who became embroiled in a scandal over his wife's murder of a British businessman and who stood trial last week for corruption and abuse of power.
The English-language South China Morning Post, quoting sources "familiar with the leadership's thinking," said China's current and retired top leaders reached the decision to investigate Zhou, who oversaw China's massive state security apparatus and served on the Politburo Standing Committee, the apex of political power.
The SCMP report said the investigation will focus on oilfield and property deals that have benefited Zhou and his family. The Hong Kong newspaper's report could not be independently verified.
Requests for comment were faxed to the State Council Information Office, the Cabinet's press office, and the Communist Party's propaganda department while calls to the Ministry of Supervision rang unanswered.

It has been several decades since a Politburo Standing Committee member has been prosecuted by China's judiciary, whether incumbent or retired. The reported investigation into Zhou, 70, may illustrate the new leadership's determination to exempt nobody in its fight against endemic corruption.
Prosecutions of high-level officials on graft charges are perceived as moves to ostracise those who have been defeated in factional struggles, without publicising details of infighting that depict party leaders in a state of disunity.
"I think that the anti-corruption effort is just a political weapon used to take down whoever they want to take down," said Zhang Lifan, a Beijing historian and elite politics expert.
"Because when there is widespread institutional corruption, anti-graft efforts are not going to clean up the system. They are a means to get rid of political opponents."
