The Enforcement Directorate has questioned former Telecom Minister A. Raja in connection with its money laundering probe in the 2G spectrum case.
This is the first time that the ED has questioned Mr. Raja in the case.
During questioning, ED investigators grilled Mr. Raja on various issues related to spectrum allocation during his tenure and also about his personal finances, sources said.
Mr. Raja, according to sources, was also questioned about his associates and their role in the grant of telecom licences.
The ED also took possession of financial documents that it had asked Mr. Raja to bring along with him for questioning, under provisions of the Prevention of Money Laundering Act (PMLA).
Sources said the former Dravida Munnetra Kazhagam minister could again be called for questioning with regard to the policy decisions taken to grant spectrum to few specific firms.
Mr. Raja had got bail in May 2012 after he was arrested by the CBI last year in the same case.
