Bank statements and financial statements seized from several offices and residences of Andaleeb have revealed discrepancies in the handling of foreign exchange. However, the clinching evidence—records that show $748,504 paid in four instalments in 2001—have continued to elude ED officials. But sources linked to the investigation say they have definite leads that could finally end in cases being slapped on Andaleeb under the Foreign Exchange Management Act (FEMA). For an export house, Hamdan’s licence "was not in order," says an official. Now, another oil company, Rotterdam-based Vitol, has also been linked to Natwar and the Congress. Apparently, Vitol issued letters of credit in the oil deal at the UN-approved Banque Nationale Paribas, Paris. One of these letters of credit is worth $16.8 million against the contract for the Congress while the other is worth almost $5.7 million.
