Special CBI Judge Ajay Kumar Jain issued open NBWs against Carlo Gerosa and Guido Haschke, the two accused, after ED's special prosecutor N K Matta said that their custodial interrogation was required as some new facts have emerged during the probe.
Matta also said that some important documents have been received from the Swiss authorities as well as from Italy and both the accused were required to be interrogated about them.
The court had earlier issued open NBW against British national Christian Michel James, an alleged middleman in the deal, on two separate pleas filed by ED and CBI.
ED had earlier claimed in the court that Agusta Westland had allegedly paid a "kickback" of around 70 million Euros, out of which around 30 million Euros was paid to James and his firm Global Services FZE, Dubai, while Gerosa and Haschke had cornered the rest.
In November last year, ED had filed a charge sheet in the case against businessman Gautam Khaitan and others, including Gerosa and Haschke.
CBI had named a number of persons in its FIR in the case who include former Indian Air Force chief S P Tyagi.
Tyagi, and others, including Gerosa, James and Haschke are among the 13 individuals named as accused in CBI's FIR.
