"After interrogating several persons so far, we have been able to identify two conspirators who are politically influential and not questioned by the agency till now," agency sources said.
Once the CBI is convinced with the nature of the evidences collected, the agency will legally start proceedings against them.
"We want to go forward on a solid footing and our intention is not to create any sensation whatsoever," the sources said.
The CBI, unlike the ED, has started the probe just over four months ago on the direction of the Supreme Court.
Because of the voluminous nature of the probe, the agency will take a fair amount of time to complete the probe, the sources said.
The CBI is preparing its first charge sheet against Saradha Tours & Travels which will probably be filed by the end of this month, the sources said.
The CBI, which is looking into the criminal conspiracy angle of the scam, has collated several documents in the course of investigations.
"I cannot say whatever is collected is all foolproof. But we are analysing all sorts of data which are provided to us," the sources said.
Alleging that the West Bengal government is going slow on providing the land records documents of the arrested Saradha chief Sudipto Sen, the sources said, "We had asked the land records department of the state government to provide us the details of Sudipto Sen's holdings".
The government has been giving information on a piecemeal basis and is yet to furnish it completely, the sources said.
Regarding painter Suvaprasanna, who was quizzed by the CBI regarding his transactions with Sen, the sources said, "He is saying that he does not remember the financial details which are looked by others."
"We need to get clarifications from him and he has to give all the details," the sources said.
Suvaprasanna, considered close to Trinamool Congress, sold his TV channel to Saradha group's Sen.
