The Central Bureau of Investigation has apprised a Delhi court of its ongoing probe into the 2G spectrum issue, according to news reports. This follows a private complaint filed by Janata Party chief, Dr Subramanian Swamy, for the trial of former Minister of Telecommunications and IT, A. Raja for his alleged role in the case.

The CBI has told the court that after registration of the case, numerous searches were conducted in the Department of Telecommunications, various private companies, besides the residential premises of various public servants and people including Raja.

It added that the searches and seizures resulted in the recovery of voluminous documents. Various witnesses have also been examined in respect of the facts of the case, the agency added.

The CBI, in its status report, however, sought to ignore Swamy?s concern over the alleged threat to national security due to allocation of spectrum to Swan Telecom, a joint venture between D B Realty and Etisalat DB, which as per his complaint is a Dubai-based firm with possible links with Pakistan?s ISI.

The CBI said it was not aware of the details on national security aspect as raised by Swamy.
