Israeli investigators raid federal ministry as part of Olmert probe

JERUSALEM (CNN) - Israeli police investigators Tuesday raided the Ministry of Industry and Trade building and seized documents related to a fraud investigation of Prime Minister Ehud Olmert, a police spokesman told CNN.

On Monday, police conducted a similar search of City Hall and other municipal offices in Jerusalem, taking documents as part of the ongoing probe.

Police are investigating whether Olmert received large sums of money illegally while he was mayor of Jerusalem and the nation's minister of industry, trade and labor. Olmert told reporters last week that he has never taken a bribe, but vowed to resign if he is indicted.
