Advancing final arguments in the case in which promoters of Essar Group and Loop Telecom are facing trial along with others, Special public prosecutor Anand Grover referred to the documents and statements of prosecution witnesses to buttress the agency's claim.
Grover told Special CBI Judge O P Saini that the materials collected by the agency during its probe corroborated that the Essar Group of companies had provided the funds for the entire transactions relating to the case.
CBI arguments today remained inconclusive and would continue tomorrow.
The CBI had earlier told the court that accused firm Loop Telecom Ltd (LTL) was "used" by Essar Group of companies to acquire 2G licences by "circumventing" the procedures.
Essar Group promoters Ravi Ruia and Anshuman Ruia, Loop Telecom promoters, Kiran Khaitan, her husband I P Khaitan and Essar Group Director (Strategy and Planning) Vikash Saraf are facing trial in the case, along with three telecom firms -- LTL, Loop Mobile India Ltd and Essar Tele Holding Ltd (ETHL).
