CBI Director Aswani Kumar today said details of irregularities in spectrum allocation would be known after the investigation into the case is over.
"Whatever had been done so far regarding the raids are in the (CBI) website," Kumar told reporters here.
The CBI had last week searched offices of the Department of Telecom and some telecom companies who were release spectrum last year in connection with allegations of irregularities in spectrum allocation.
The searches had prompted Opposition parties to demand resignation of Telecom Minister A Raja.
Raja has been facing the charge that he doled out spectrum cheaply to new players that may have caused a loss of Rs 22,000 crore to the government.
Raja had denied the charges and has ruled out quitting office. He has been maintaining that he has done no wrong and had only followed the prescribed procedures after consultation with the Prime Minister.
The CBI Director was here on a visit to the Madurai Bench of the Madras High Court.
