CBI today filed fresh status report in a sealed envelop in the Supreme Court on coal block allocation scam. The report gives details of the ongoing probe into the scam in which companies, business tycoons and bureaucrats have come under its scanner.

The apex court had directed CBI to conclude the probe against all companies, which were allocated coal blocks, by December this year.

After the last hearing a fresh FIR has been filed by the agency against industrialist Kumar Mangalam Birla, his company Hindalco and former coal
secretary P C Parakh. The FIR alleged that the then coal secretary had overturned his decision while
allotting the block to Birla's company.
