The probe into the chopper scam after conviction of former heads of Finmeccanica and AgustaWestland by an Italian court changed “the understanding” of the investigating agency regarding the Rs 3,600 deal which was allegedly clinched after bribing some Indians, the sources said.The sources said the judgement by the Milan Court of Appeals has “made it clear” that bribes were paid by UK-based AgustaWestland, a sister concern of Italy’s Finmeccanica.The SIT will now probe who were the beneficiaries of the kickbacks and ascertain the chain of fund flow. Responses to Letters Rogatory sent in this regard are awaited. Another case the SIT would probe relates to alleged diversion of loans of thousands of crores of rupees taken by Kingfisher Airlines to their foreign accounts.
