Enforcement Directorate (ED) on Wednesday filed a chargesheet against Christian Michel James and two other alleged middlemen of Agusta Westland VVIP chopper scam.
He is amongst the three alleged middle men being probed in the case by the ED and CBI both.
Earlier this, ED summoned some Indian contacts of British national Christian in connection with its money laundering probe in this Rs 3,600 crore Agusta Westland VVIP Choppers deal.
ED had registered a Prevention of Money Laundering Act (PMLA) case in this regard in 2014 and named 21 people including former Indian Air Force Chief S P Tyagi in its money laundering FIR.
It had also arrested Delhi-based businessman Gautam Khaitan and had also filed a charge sheet last year.
Officials said few people involved in creating an overseas firm with Mitchel have been called by the agency to record their statements under the provisions of the PMLA this week.
The agency wants to understand the 'financial relationship' of at least three people who had created an offshore entity with Mitchel, approximately around the same time when the 12 choppers deal was being finalized and was in final stages of execution.
