New Delhi: Prime Minister Manmohan Singh on Saturday directed the CBI to thoroughly investigate high-profile cases like 2G and CWG scams and produce quick results and bring the guilty to book without any fear.

"The handling of these cases constitutes a litmus test for you," Prime Minister told the top brass of the CBI at a function to inaugurate the new CBI headquarters.

However, he did not specifically refer to the 2G or Commonwealth scams in which the agency has arrested top corporate honchos as well as sacked chairman of CWG Organising Committee Suresh Kalmadi and former Telecom Minister A Raja.

Describing these as "high-profile" cases, PM said in his forthright address that "the CBI should act without fear or favour and bring to book all those who are guilty, irrespective of their position or status.

"I would advise the CBI to put your heads down and work hard, away from the media glare, to ensure early resolution of these cases," Prime Minister said.

He also referred to his address at the Civil Services Week during which he had spoken about the problem of corruption and the growing "impatience of our people to see quick action for tackling it".

"The CBI is today investigating many high profile cases of corruption that have attracted a great deal of public attention," he said, adding "what is expected of you is thorough investigation, fair action and quick results."

"Ours is an open and free society. There will be many views and opinions on all issues. The CBI has to be sensitive to these but it has always to do what is right and correct," he said.

The PM cautioned the CBI that there should be no vendetta, no witch-hunt and no harassment of the innocent. "There should be no apprehension of punitive action for bona fide mistakes as we cannot afford an environment that breeds fear, inaction and indecision,” he mentioned.

“Trials have also to be conducted, and conducted speedily. We have decided to set up 71 additional special courts for dealing with cases entrusted to the CBI. I am told that 64 of these have now been sanctioned but only 16 are operational," he said.

The government remains committed to give the CBI "necessary independence and operational flexibility" besides providing it manpower, finances and the technology that the agency requires, Singh said.

He said the officers, men and women working in the CBI have a difficult task to perform and it was "essential that they are looked after well and they have the necessary technical and other resources required for their work."

"I would urge the officers of the CBI to strive tirelessly to set even higher standards of work," the Prime Minister said.

Union Home Minister P Chidambaram, Telecom Minister Kapil Sibal, National Security Advisor Shiv Shankar Menon, senior bureaucrats including Cabinet Secretary K M Chandrasekhar and Home Secretary G K Pillai were present at the function.
