The Central Bureau of Investigation (CBI) on Tuesday summoned former Coal Secretary P.C.Parakh for questioning in connection with a case for alleged abuse of his official position in granting a coal block in Odisha to Hindalco.
Official sources today said Parakh has been asked to appear before the agency this week.
The investigation agency had last year registered a case against Parakh, unknown officials of Hindalco and coal ministry.
Parakh is accused of favouring Hindalco by changing the allotment of Talabira-II coal block as against the Screening Committee's recommendation in favour of Public Sector Undertaking Neyveli Lignite Limited.
