NEW DELHI: Enforcement Directorate on Tuesday searched six premises in connection with a case of money laundering against Anil Ambani and R-ADAG entities.Sources said the searches were a part of the investigation into overseas remittances by Reliance Infrastructure, allegedly in violation of certain regulations of Foreign Exchange Management Act (Fema).In a statement, Reliance Infrastructure said Tuesday’s searches were related to matters dating back to 2010, when the company had awarded an EPC contract for construction of JR toll road (Jaipur-Ringas highway) to Prakash Asphaltings & Toll Highways.“This was a domestic contract with no foreign exchange involved. The work was completed, and the company has no continuing connection or relationship with the said contractor. The toll road has been with NHAI for the last four years,” it said, adding that the company and its executives are fully cooperating with ED in its probe.On Aug 5, Ambani was questioned at ED headquarters in connection with another money laundering probe against him and his entities, and his Cuffe Parade residence was searched by CBI on Aug 23 as a follow-up of an FIR registered by the anti-corruption agency for alleged “misappropriation of funds” received from SBI.During his visit to ED headquarters, Ambani was asked about his foreign assets and other transactions, both in India and overseas. Some of his other close associates have also been questioned over the past two months in the same case.ED is probing alleged laundering of public money exceeding Rs 20,000 crore, some of which was allegedly siphoned outside the country through “undisclosed foreign bank accounts and foreign assets” created over the years.
