The multi-crore deal to purchase AgustaWestland choppers for VVIPs was scrapped by India over allegations of corruption and kick backs being paid in the deal.
Christian Michel was extradited from Dubai last year and is currently lodged in Tihar Jail in connection with alleged irregularities in the AgustaWestland VVIP chopper deal.
The money laundering case was lodged following alleged irregularities in purchase of 12 VVIP choppers from Italy-based Finmeccanica's British subsidiary, AgustaWestland.
The ED's counsel told the court that Puri was evasive throughout the questioning and sought eight days custody.
Special Judge Arvind Kumar rejected Michel's applications in cases filed by the CBI and the ED, saying there was no sufficient ground to grant the relief.
Special Judge Arvind Kumar remanded Puri to ED's custody till September 11, noting that the probe agency has sought his custodial interrogation to 'unearth the source and end-use of tainted money.'

Ratul Puri is already in the custody of Enforcement Directorate in the alleged bank fraud case related to his company Moser Baer.
The CBI court said Ratul Puri failed to join the probe despite repeated notices of the Enforcement Directorate.
Justice Mukta Gupta said the reply should be filed within three weeks and listed the matter for further hearing on October 9.
The agency made the allegations before special judge Arvind Kumar who was hearing Puri's application seeking cancellation of a non-bailable warrant against him.
Christian Michel has cited the orders from an Italian court as one of the grounds in his applications seeking bail in both the cases filed by the ED and the CBI.
Puri, who is being questioned by the ED in the AgustaWestland VVIP chopper deal case, had on July 26 escaped on the pretext of going to the washroom, said an agency official.
The court granted the interim protection till next Tuesday, when it would further hear Puri's plea challenging a trial court's order denying him anticipatory bail.
CBI had told the court that Christian Michel made 24.25 million euros and 1,60,96,245 pounds from the now-scrapped Rs 3,600 crore AgustaWestland deal.
The ED said he did not join the probe on July 29, 30, 31 and further on August 6 and 7, nor was he accessible on phone or at his residence and that his whereabouts were not known.
