Prosecuting authorities are investigating two local officials suspected of corruption, the Supreme People's Procuratorate said Wednesday.
Zhang Yu, formerly an Inner Mongolia official in charge of researching the history of the Communist Party of China, was arrested over allegations of embezzlement.
Ou Aiguo, former general manager of the Hunan Hotel, was accused of accepting bribes and is subject to "coercive measures".
Coercive measures may include summons by force, bail, residential surveillance, detention and arrest.
Investigation into their cases is underway.
