The Central Bureau of Investigation, CBI, has sought more time to clarify queries posed by a Delhi court in closure report filed against Kumar Mangalam Birla and others in a coal scam case.

CBI told the Delhi court that due to Supreme Court's order, it will not file any further supplementary final report in coal scam cases.

On the 12th of this month, a special court had asked the CBI as to what was the hurry in filing a closure report in the coal blocks allocation case in which it had earlier lodged an FIR against top industrialist Kumar Mangalam Birla and others.

During the hearing, the Investigating officer had told the court that original minutes of the screening committee meeting in which Birla-owned Hindalco's application seeking coal blocks allocation was dealt with, were missing.
