(ANSA) - Bologna, October 2 - Italian finance police raided Emilia-Romagna regional offices on Tuesday, in a search for evidence for probes opened last Friday by Bologna prosecutors into the region's handling of public funds. The prosecutors, who cite no specific wrongdoing, are already investigating Paolo Nanni, the Bologna provincial leader of the anti-corruption party Italy of Values (IdV), for allegedly mishandling party money. The inquiry was announced shortly after police searched party offices at the Piedmont regional administration on Friday in a preliminary inquiry into suspected over-spending by various caucuses. They are the latest in a string of national anti-corruption moves following a wave of scandals that led to the arrest of the caucus leader of Silvio Berlusconi's People of Freedom (PdL) party in Lazio, Franco Fiorito, on Tuesday. Lazio governor Renata Polverini quit earlier this week after mounting pressure forced her to hand in her resignation. Regional and national politicians have vowed to revise regional spending laws.
