The CBI has roped in the Enforcement Directorate to help it in locating the money trail and violations of Foreign Exchange Management Act and stake-holding patterns in some of the firms which acted as front for other telecom companies

New Delhi: Zeroing on the criminal conspiracy relating to the second generation (2G) scam among corporates, the Central Bureau of Investigation (CBI) is preparing a list of all ineligible telecom companies which had got the licences in 2008, reports PTI.

Besides, the agency is conducting a "microscopic examination" of a deal between Tata Group's real estate and infrastructure development arm Tata Realty & Infrastructure and Unitech whereby the latter had received a loan, which the agency claims, have been diverted, official sources said.

Corporate lobbyist Niira Radia is likely to be summoned again to the CBI in connection with the case for allegedly playing an important role in the deal, they said.

The CBI has roped in Enforcement Directorate (ED) officials to help it in locating the money trail and violations of Foreign Exchange Management Act (FEMA) and stake-holding patterns in some of the firms which acted as front for other telecom companies.

Sources said the CBI has decided to send Letters Rogatory (LRs) to two countries-Cyprus and Norway-to find out source of funding of telecom firms who were awarded spectrum.

A Letters Rogatory is a formal request issued by a competent court to a foreign court and processed by the ministry of external affairs on behalf of the investigative agencies to obtain information about individuals and entities.

"A list of ineligible firms is being drafted and its findings on criminal conspiracy/culpability will be finalised within two weeks' time," a CBI official said.

The CBI, which has been directed to file a charge-sheet by 31st March by the Supreme Court, is likely to question DMK MP K Kanimozhi, the daughter of Tamil Nadu chief minister K Karunanidhi, in connection with the scam, they said.

Sources said CBI sleuths have found irregularities in funding Rs214 crore to Kalaignar TV, a regional channel operational mainly in Tamil Nadu in which Karunanidhi family members allegedly have majority stakes, by DB Realty.

Earlier, the CBI had questioned R Krishna Kumar and Sanjay B Ugale, chairman and managing director, respectively, of Tata Realty & Infrastructure and Anil Sardana, former CEO of Tata Teleservices Ltd.

The CBI had also questioned Sanjay Chandra of Unitech on issues relating to offloading of majority stake to Norway based company Telenor after getting 2G spectrum license.

The agency is probing whether Tata Real Estate had paid Rs1,600 crore to Unitech for a land deal at a time when the real estate company was applying for 2G licence in 2007.

The Comptroller and Auditor General (CAG) had in its report presumed losses to the tune of Rs1.76 lakh crore in distributing spectrum to certain telecom firms due to certain procedural lapses.
