The Enforcement Directorate has questioned former Telecom Minister, Mr 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 under his Ministership and also about his personal finances, sources said.
Mr Raja, according to sources, was also questioned about his Ministry 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 the provisions of the Prevention of Money Laundering Act.
The sources said the former DMK Minister could again be called for questioning with regard to the policy decisions taken while granting spectrum to few specific firms.
Mr Raja had got bail in May this year after he was arrested by the CBI last year in the same case.
