CBI has concluded its probe in six FIRs related to allocation of coal blocks and is likely to intimate the Supreme Court about it in its upcoming status report on Monday.
While the sources remained tightlipped about the specific cases in which investigations have been completed, they said they were in the proces of finalising six cases.
After the last bit of scrutiny and completion of technical formalities, the agency may go ahead with filing its final report before the competent courts, they said.
CBI has registered 14 FIRs so far in connection with the alleged graft in allocation of coal blocks in which AMR Iron and Steel, JLD Yavatmal Energy, Vini Iron and Steel Udyog, JAS Infrastructure Capital Pvt Ltd, Vikash Metals, Grace Industries, Gagan Sponge, Jindal Steel and Power, Rathi Steel and Power Ltd, Jharkhand Ispat, Green Infrastructure, Kamal Sponge, Pushp Steel, Hindalco, BLA Industries, Castron Technologies and Castron Mining have been named.
The Supreme Court is monitoring the probe in the coal scam to "restore the larger public interest and confidence of the people into the case of this magnitude".
The court is scrutinizing coal blocks allocation since 1993 on three PILs seeking cancellation of blocks on the ground that rules were flouted in giving away the natural resource and that certain companies were favoured.
