New Delhi: Facing CBI probe in the 2G spectrum allocation scam, the Tata Group and Anil Dhirubhai Ambani Group had applied for two kinds of licenses. On the one hand, both companies had applied for dual technologies license, on the other they had also applied for spectrum through Swan and Unitech. Both, however, withdrew from these companies after their own bids won dual technologies license.

According to a senior officer involved in the investigation, both Tata and ADAG were trying to win spectrum license for a long time.  But before they could apply, the government had decided to allocate 2G spectrum to some companies. With uncertainty prevailing over dual technology license, the two companies tried to secure the same through front companies.

CBI probe has revealed that while Tata Group used Unitech as a front company. The group paid Unitech a sum of Rs 1700 cr to buy a plot in Haryana as a part of their deal. This sum is equal to the license fee for 2G spectrum. However, in 2008, when the Tatas won license for 2G, they annulled their agreement with Unitech and also withdrew the advance amount.

ADAG tried to win GSM license through Swan Telecom in which it bought 10 per cent stake. Tigers Traders, the majority stake holder in Swan, are also under scanner.  They claimed in their application that they were the trustee of Indian Telecom Infrastructure Fund. If the CBI is to be believed, no such fund exists.

Companies from Mauritius have largely invested in Tigers Traders and the look-out for its real owners is underway.

In October 2008, the Anil Ambani Group won dual technology use license and withdrew stake from Swan.
