New Delhi (Agencies): Janata Party chief Subramanian Swamy, in his complaint to a Delhi Court, on Saturday named DMK chief and Tamil Nadu CM M Karunanidhi as a co-accused along with former Communications Minister A Raja in the 2G spectrum scam.

He strongly pleaded for continuance of his private complaint in the 2G spectrum case before the court, which asked him whether there can be "parallel proceedings" in a criminal case when CBI was taking action in the matter.

Swamy sought to claim that his complaint covers wider canvas of "involvement" of Tamil Nadu Chief Minister K Kruananidhi in the scam and national security.

Swamy sought to claim that that his complaint covers wider canvas of "involvement" of Tamil Nadu Chief Minister K Kruananidhi in the scam and national security.

He was responding to a pointed query of Special Judge Pradeep Chaddah as how parallel proceedings can continue on the same issue when "media reports" suggested that CBI was probing the case and has also arrested former Telecom Minister A Raja and two top officials in the case.

"As per section 210 of the CrPC, when it appears to the magistrate that the police (CBI) investigation is in progress in relation to some matter, the complaint case, which is pending before him, then he must stop the proceedings and call for reports," the court said while asking the agency to file a detailed report on February 22.

Earlier, Swamy said "the scope of the private complaint was much wider than what is being investigated upon by the CBI and as per my knowledge, the complaint also involves concerns of national security and involvement of Karunanidhi."

The Janata Party leader said that he was intending to file an application seeking impleading of the Tamil Nadu Chief Minister as an accused in the case as there was sufficient evidence to that effect.

The court asked the CBI, which is presently interrogating Raja, former Telecom Secretary Siddartha Behura and Raja's former Personal Secretary R K Chandolia in its custody, to file a "detailed report of the investigation being carried out by it and whether it covers the aspect of national security as raised by Subramanian Swamy in the present case".

Comptroller and Auditor General Vinod Rai, who was earlier summoned by the court to appear as witnesses on Swamy's complaint, filed a certified copy of the entire report concerning the matter through his advocate Sandeep Sethi.

The Special CBI judge had on January 22 sought presence of Rai and Director CAG R P Singh in the court to depose as witnesses on the complaint by Swamy seeking registration of a criminal case against Raja for his alleged role in the scam, which, according to the CAG, caused a presumptive loss of Rs 1.76 lakh crore to the exchequer.

However, the CBI, while seeking custody of Raja and two other top officials, has accused the DMK leader of causing a loss of Rs 22,000 crore to the exchequer by favouring some telecom firms in award of the 2G spectrum licences.

During the hearing, the special judge today said, "I am of the opinion that this court should not proceed for the time being with this matter."

Swamy, however, defended his complaint and said at the later stage, the two cases can be clubbed and tried together.

The court had on January 7 held as "maintainable" the private complaint filed by Swamy on December 15 last year.

He had pleaded that his complaint be taken cognizance of and Raja be summoned to take the case to its logical conclusion. Swamy also requested the court to appoint him "as a deemed public prosecutor under the provisions of the Prevention of Corruption Act."

Swamy also wanted the court's directions to agencies like the CBI and Enforcement Directorate (ED) to assist him in conducting prosecution and in further investigation into the scam.

Quoting from the CAG report, Swamy had alleged that Raja committed fraud by adopting the first-come-first-served criterion to allocate spectrum to ineligible companies.
