Italy's state-controlled AgustaWestland had allegedly kept aside Rs 217 crore as part of "corrupt activity" to bag India's Rs 3,600 crore deal and its choppers became eligible only after certain required parameters were altered in the tender document.

According to the report filed by Italian investigators in an Italian court, the middlemen had agreed for a 7.5 per cent commission in the Rs 3600 crore for 12 VVIP helicopters.

Finally, the kickbacks were to the tune of about Rs 362 crore. The payment of bribes through contracts between firms registered in Tunisia and India, was "still underway" when the scam was unearthed.
