The CBI will soon send a formal request to Switzerland to help the agency in tracking down the alleged money trail of Swan Telecom, a company charge-sheeted in the allocation of 2G spectrum.
CBI sources said this was decided after documents received from Mauritius indicated flow of money to other European countries considered as tax havens.
Letters Rogatory
They said Letters Rogatory (LR) will be sent to Switzerland authorities to share investigation details in the allotment of second generation spectrum in 2008.
If the Swiss authorities agreed, a joint team of CBI and Enforcement Directorate would be sent to the European country for carrying out investigations, the sources said.
“We have received ownership patterns and details of investments by a number of companies based in Mauritius. Prima facie it appears that funds have been routed to Switzerland through some channels. We are still examining all documents and will send our team to probe it,” a CBI official said.
