The Central Bureau of Investigation has moved a Delhi court, seeking permission to interrogate alleged AgustaWestland middleman Christian Michel in Tihar Central Jail, where he is lodged.
Special Judge Arvind Kumar sought response from Michel on the application by September 20, when the court will hear the matter.
In its plea, the CBI also sought specimen of Michel's signature and handwriting for probe.
The agency has told the court that Michel needs to be confronted with some more documents.
The court directed Michel to be produced before it on September 20. It recently denied bail to Michel.
Michel, extradited from Dubai, was arrested by ED on December 22 last year.
On January 5 this year, he was sent to judicial custody in the ED case. He is also lodged in judicial custody in another case registered by CBI in connection with the scam.
Michel is among the three alleged middlemen being probed in the case by the Enforcement Directorate and the CBI. The other two are Guido Haschke and Carlo Gerosa.
