Su Shulin, former governor of east China's Fujian Province, has been put under investigation on suspicion of accepting bribes, the Supreme People's Procuratorate (SPP) announced on Tuesday.
Su, also former deputy chief of the Communist Party of China (CPC) Fujian provincial committee, was expelled from the CPC and dismissed from public office for violating the Party's code of conduct and corruption on July 4.
The SPP also announced an investigation into four other officials for taking bribes: Yang Chongyong, a former senior legislator in northern China's Hebei Province; Wang Yincheng, former president of the People's Insurance Company (Group) of China Limited (PICC); Zhou Chunyu, vice governor of east China's Anhui Province; and Cai Xiyou, former general manager of state-owned chemical firm Sinochem Group.
The five have been placed under "coercive measures," which may include summons by force, bail, residential surveillance, detention or arrest.
Investigations into their cases are currently under way, according to the SPP.
