The Central Bureau of Investigation continued to question for the second day on Thursday Christian Michel, the alleged middleman in the graft-tainted Rs 3,600 crore AgustaWestland VVIP chopper deal, officials said.
They said the team asked him to corroborate various contracts he had signed with Finmeccanica and AgustaWestland and the payments received from these companies.
Michel, 57, is under constant medical observation with a team deployed to monitor his health parameters, they said.
He was given normal Indian food from the CBI canteen as per his nutritional requirements, they said.
The agency is maintaining in letter and spirit the orders and procedures of custodial interrogation, they said, adding that he was given enough time to sleep and relax tonight.
The CBI has also received request for consular access to Michel from the British High Commission through the External Affairs Ministry which is under process, CBI spokesperson Abhishek Dayal said.
The officials said there are a lot of documents which the agency had received from the Italian authorities which were probing the matter earlier, besides the material collected by it during the searches.
A lot of material needs corroboration and his questioning will also fill gaps in money trail of bribe amount, they said.
The sources refused to comment if Michel was cooperating, but said he is answering the queries of the investigating team.
The agency has alleged that Michel has evaded any probe in the matter which puts him on a different pedestal than Guido Haschke -- another middleman -- who faced trial in Italy and entered in plea bargain.
The CBI had filed a charge sheet against him in September last year. -- PTI
