The ED officials said the house of its former officer Gurnam Singh, advocate Puneet Shrma and an another person in Chandigarh and Mohali are being raided since morning, under provisions of the Prevention of the Money Laundering Act (PMLA).
The raids have been launched to gather more evidence in this context, they said.
The agency had conducted multiple searches in this case last year and it had also arrested the absconding agent of the alleged chit fund firm under scanner-- Kamal K Bakshi-- under the anti-money laundering law.
The case, the ED had said, pertains to thousands of investors who were "systematically lured and cheated to the tune of more than Rs 600 crore by floating ponzi or pyramid schemes assuring exorbitant returns".
It had said that the alleged "mastermind" of the scheme is a Malaysian identified as Mugundhan Gangam who floated two firms -- Ms Unipay 2U Marketing Private Limited and Unigateway2U Trading Private Limited -- in India.
Describing the modus operandi of the alleged cheating in this case, the agency said the early investors of the ponzi schemes floated by the firm were paid exorbitant returns in order to win over their confidence.
"When thousands of people across the country invested crores of rupees in the said ponzi schemes, the companies stopped the payouts or monthly returns (since October, 2010) and gradually siphoned off crores of rupees of investors," it had said.
"The company manipulated by using a web of bank accounts and layering of money through a plethora of such accounts," the ED alleged.
The agency had registered a criminal FIR in the case, based on an earlier complaint of other central investigative agencies.
