The Enforcement Directorate (ED) on Saturday arrested Christian Michel, the alleged middleman in the AgustaWestland VVIP chopper deal case.

Michel was produced before special judge Arvind Kumar in a Delhi court and the ED 15 days' custody for the alleged middleman.

The judge allowed the ED to interrogate the British national inside the courtroom for 15 minutes after the agency sought his custodial interrogation. He was arrested after that.

Michel had been arrested in the UAE and extradited to India on December 4. The next day, he was produced before the court, which allowed his five-day custodial interrogation by the CBI. It was extended by five more days, and later for another four days.

The court had reserved the order on Michel's bail plea on December 19 and had sent him to judicial custody till December 28.

Michel is among the three alleged middlemen being probed in the case by the Enforcement Directorate and the CBI. The others are Guido Haschke and Carlo Gerosa.

The CBI has alleged there was an estimated loss of 398.21 million Euros (about Rs 2,666 crore) to the exchequer in the deal that was signed on February 8, 2010 for the supply of VVIP choppers worth 556.262 million Euros.

The ED, in its chargesheet filed against Michel in June 2016, had alleged that he received 30 million Euros (about Rs 225 crore) from AgustaWestland.
