Last April State Comptroller Micha Lindenstrauss advised Mazuz to launch a criminal investigation against Olmert for suspicions that he appointed Likud cronies to ministerial posts during his tenure as Industry, Trade and Labor minister.
Mazuz said the probe into these suspicions, as well as into those involving the PM's purchase of a home on Cremieux Street in Jerusalem, was nearly completed.
Olmert is being probed for the purchase of the apartatment about a year-and-a-half ago, after reportedly receiving a $320,000 discount in exchange for expediting construction permits.
The attorney general said the examination of Olmert's alleged involvement in the privatization of Bank Leumi was being handled by the state prosecutor's office.
In January, the National Fraud Investigation Unit opened an investigation of the sale of Bank Leumi's controlling shares and the prime minister's alleged bribery offenses in the sales tender.
