The agency will also be sending a judicial request to Italy for detailed information on the statements given by the accused that are in the custody of the authorities there.
They said after getting the statements, the agency would explore the option of seeking extradition of all the accused who are in the custody of Italian authorities.
However, at the moment, there is no such move, they said.
The helicopter contract is under probe of Italian and Indian agencies for alleged kickbacks paid to Indian officials - including former IAF chief S P Tyagi - to clinch the deal.
