The Enforcement Directorate (ED) quizzed former Telecom Minister A Raja in connection to the 2G spectrum allocation scandal, media reports said on Thursday.
This is the first time the ED quizzed Raja in connection to the scam.
According to reports, Raja was questioned on several issues connected to the spectrum allocation during his tenure.
The ED also took possession of the financial documents that it had directed Raja to bring with him during questioning.
A special Central Bureau of Investigation (CBI) court on May 15 granted bail to Raja who was languishing in the Tihar jail for 15 months in the 2G case.
Raja, who was arrested in 2011 for his alleged role in the scam, had applied for bail in the court on May 9.
Touted to be the biggest corruption scandal of independent India, the 2G scam, allegedly masterminded by Raja, pertains to a biased distribution of mobile airwaves and operating licenses, in lieu of kickbacks, to telcos that could have cost the treasury up to Rs 1.76 lakh crore in lost revenue, according to the government´s auditors CAG.
