Narayanan, one of the accused in the infamous Chopper deal scam, has been grilled by the investigative agency -- Central Bureau of Investigation (CBI) on Friday, June 27. The CBI questioned Narayanan in Kolkata.
The agency earlier had requested Law Ministry during UPA regime to allow them to question Narayanan and his counterpart in Goa -- BV Wanchoo. The CBI has been investigating the alleged kickbacks in the Rs 3600-crore VVIP helicopter deal.
The government terminated the deal for 12 helicopters alleging that AgustaWestland, the British subsidiary of an Italian company contracted to supply the helicopters for use by the President, Prime Minister and other VIPs had breached an integrity pact by allegedly paying bribes to Indian officials.
CBI sources had said Narayanan, who was then the National Security Adviser or NSA and Wanchoo as head of the elite Special Protection Group or SPG, were part of meetings where specifications for the helicopters were changed.
The change in "service ceiling" (or the altitude at which a helicopter can fly) from the 6000 metres suggested Air Head Quarters to 4500 metres had allowed AugustaWestland to enter the race.
