The CBI on Thursday grilled corporate lobbyist Niira Radia for several hours at its headquarters in connection with 5,800 telephonic intercepts of her conversations, some of which were allegedly linked to the irregularities in allocation of 2G spectrum and licences in 2007-08.
The CBI questioned Radia to seek clarifications and contexts regarding certain conversations that allegedly suggested she had played a role in facilitating allocation of 2G spectrum and licences to a few telecom companies, said a CBI source. The agency has transcribed the taped conversations but needs to fill gaps to understand the decision-making processes behind the allocations, the source added.
Radia's spokesperson refused to comment.
"There was a money-trail that we are trying to establish," said the CBI source. The agency suspects the money-trail in the spectrum scam is allegedly spread across several countries including Mauritius, Singapore, Sierra Leone and Senegal.
The CBI had grilled Radia on Tuesday too and had carried searches at her New Delhi residence in December.
The agency has already grilled former Telecom minister A Raja to establish his alleged role in the irregularities in the allocations by the Department of Telecommunications.
The allocation had violated several norms and was carried out in a manner intended to favour a few select groups of applicants, said the officer.
The CBI is also verifying if those allotted spectrum and licences had allegedly influenced Raja's decision to price the licences at rates prevalent in 2001, without revising them for 2008.
