Police raided Jerusalem's City Hall on Monday, searching offices and confiscating documents as part of a widening corruption investigation against Prime Minister Ehud Olmert. Olmert is suspected of illicitly accepting large sums of cash from a Jewish American donor. Some of the donations are believed to have taken place during Olmert's 10-year tenure as mayor of Jerusalem. Police spokesman Micky Rosenfeld said the police's National Fraud Squad conducted Monday's raid. He said the seized documents were connected to Olmert time as mayor between 1993 and 2003, but had no further details on their contents.
