The police's National Fraud Unit on Thursday advised that not enough evidence had been found to proceed with criminal charges against Prime Minister Ehud Olmert in the 'Cremieux Street' affair. Attorney-General Menahem Mazuz has already announced his intention to indict the prime minister in three separate affairs - the 'Investment Center' case, the 'cash envelopes case' and the 'Rishon Tours' case - pending hearings. Lahav Unit (433) chief Cmdr. Yoav Saglovitch said Thursday that the investigation had not yielded sufficient results, and that the case file would be passed on to Mazuz for his consideration. The probe investigated claims that Olmert had received favorable terms for the purchase of a home on Jerusalem's Cremieux Street, in return for helping the contractor who sold it to him.
