A court here on Saturday sent former Air Force chief SP Tyagi and two others to judicial custody till December 30 in Rs 3,767 crore AgustaWestland chopper deal case.
Tyagi along with other accused in the case were produced before the Patiala House court today as their CBI custody ended.
The court had earlier on December 14 extended till December 17 the CBI custody of Tyagi, his cousin Sanjeev Tyagi and Delhi lawyer Gautam Khaitan.
The trio was arrested on Friday. On Saturday, they were remanded in CBI custody till December 14.
Earlier on Wednesday (Dec. 14), the CBI had sought seven-day extension in custody of Tyagi and others, saying their custodial interrogation is necessary in the interest of justice as it has yet to unearth the entire conspiracy.
The agency has claimed that a confidential document of the government was seized from the residence of alleged middleman and Italian national Guido Haschke's mother.
The CBI said that the document regarding a proposal to amend the VVIP helicopters' configuration was seized from Haschke's mother's house in Switzerland and it needed to be probed.
The document pertains to the proposal to reduce the service ceiling of the helicopters from 6,000 metres to 4,500 metres after which AgustaWestland became eligible to supply a dozen helicopters for VVIP flying duties.
Tyagi -- the first former chief of any wing of the Indian armed forces to be arrested -- and others were allegedly involved in irregularities in the procurement of 12 AW-101 VVIP helicopters from Britain-based AgustaWestland.
