acquire the 12 three-engine AW-101 helicopters from AgustaWestland for IAF's elite Communication Squadron, which ferries the President, PM and other VVIPs.
With the scam unfolding in the deal, the delivery of three helicopters from AgustaWestland scheduled for next month has been put on hold along with the remaining six which were to arrive later.
India has already received three of the 12 helicopters.
A CBI team is also being sent to Italy where the CEOs of AgustaWestland and its parent company Finmeccanica have been arrested on charges of bribery.
