New Delhi: In a bid to tighten the noose around former Telecom Minister A Raja and ex-Telecom Secretary Siddhartha Behura, the Central Bureau of Investigation (CBI) is soon going to file a chargesheet against them. The duo has been accused of giving clean-chit to Essar-Loop in the 2G spectrum allocation scam.

In another round of grilling, which lasted for three hours in Patiala House Court complex, the CBI on Monday questioned Raja and Behura in connection with the Essar-Loop nexus.

After the interrogation, a CBI official revealed that former Telecom department’s Legal Advisor Santok Singh is also involved and will be charged soon.

CBI sources said, “An important clause in the 2G spectrum allocation states that the company providing the mobile services cannot apply for the licenses directly or indirectly i.e. with the help of any associate company.”

However, both Essar and Loop through mutual consent violated this norm.

Notably, Raja and Behura and Singh came under CBI scanner after a written complaint was lodged with DoT to cancel their licences.

The Corporate Affairs Ministry also recommended canceling the licences of Loop by calling it a front company of Essar. However, the former Telecom Minister instead of agreeing to the advice, agreed to the suggestion made by Santok Singh, who gave a clean chit to Loop Telecom following which Raja and Behura also gave a green signal to the Essar group company.
