Investigating kickbacks in the $208 million (Rs 1,350 crore) Embraer aircraft deal, the CBI team had collected important documents from the United States, where its department of justice is probing Embraer's violation of the Foreign Corrupt Practices Act.
CBI sources said that a team had recently went to the US to gather evidence on Embraer which could be used to prove the corruption charges in the deal signed in India. "The documents are now being scrutinized," said the officer.
CBI has found out that more than 5.70 million dollars had been paid as kickbacks in the contract and these have been linked to Khanna, said sources.
The deal for the three aircraft which were to be used by the Defense Research and Development Organisation (DRDO) for air borne radar systems was inked with Embraer in 2008.
