Israeli police say Prime Minister Ehud Olmert's personal secretary has been placed under house arrest for 10 days as part of a corruption probe - the latest political scandal to rock the Jewish state.
A spokesman says Shula Zaken was among more than 15 people questioned Tuesday in an investigation into government officials accepting or giving bribes in return for tax breaks.
Tax officials were among those questioned.
Reports say Mr. Olmert has not been targeted in the probe.
The Israeli prime minister has been the subject of several previous corruption investigations but has not been charged.
