Occupied Jerusalem: Israeli police on Sunday raided government offices in connection with criminal investigations of Prime Minister Ehud Olmert, a police spokesman said.

The investigators were searching for evidence related to three separate investigations of Olmert, police spokesman Micky Rosenfeld said.

They fanned out early Sunday in more than 20 different locations, including the Industry and Trade Ministry, the Postal Authority, and Jerusalem City Hall, he said.

Olmert is facing three criminal investigations in real-estate and political corruption cases.

One involves suspicions that he steered a government grant to a friend and arranged improper political appointments while serving as trade minister earlier this decade.

Another is tied to allegations he tried to rig the sale of Israel's second-largest bank in favor of two associates while he was finance minister, and a third concerns his involvement in a real-estate deal in which he is suspected of buying a home in Occupied Jerusalem at a substantial discount from a developer in exchange for arranging construction permits for the builder.

Olmert has denied all the charges. No comment was immediately available from his office Sunday.
