PARMALAT Finanziaria’s former chief financial officers Fausto Tonna and Luciano Del Soldato are among six executives arrested by the Italian police today as part of a probe into the collapse of Italy’s largest food company, sources familiar with the investigation said.

PARMALAT, the Italian dairy giant, said it will file for bankruptcy protection after the Italian government passed an emergency measure to speed the restructuring of the country’s biggest food company.
