The agency, sources said, has tracked the trail of money to a few locations and banking channels in the United Arab Emirates (UAE), Dubai, Hong Kong and China in connection with the high-profile case that was unearthed by the agency in the popular diamond town of Gujarat sometime back.
"Letters Rogatory (judicial requests) will be sent to a few countries in the Middle-East to get the exact details of the illegal transactions. A competent court will soon be approached seeking permission in this regard," an official privy to the development said.
The role of a large private bank, located in Surat and Mumbai, is also under the scanner of the agency as sleuths detected large amounts of international payments were being dispatched from its portals without proper Know Your Customer (KYC) checks being done, sources said.
The central probe agency has brought under its scanner a number of businessman, including Afroz Fatta, regarding its probe under money laundering laws in this case.
The agency's zonal office in Surat, in March, had claimed to have busted a Hawala racket to the tune of Rs 700 crore during searches at the offices of some diamond traders in this city.
