CBI sources said Jindal, who has been named as accused along with the former Minister for State for Coal Dasari Narayan Rao in its 13th FIR, would be questioned this week.
According to the FIR, Jindal Steel and Power Limited and Gagan Sponge Iron Ltd, also a firm belonging to Jindal, had bagged Amarkonda Murgadangal coal block in Jharkhand in 2008 by alleged misrepresentation of facts when Rao was the Minister of State for Coal.
After Jindal's return from abroad on June 20, CBI completed its search operation as during the searches conducted on June 11, the agency could not open some of the cupboards and almirahs which were locked.
Head of External Affairs at JSPL, Manu Kapoor had earlier said, "JSPL, as a law abiding company, is governed by a strong ethical code of conduct. This is an ongoing CBI investigation into coal block allocation. At this stage of investigation, JSPL is committed to fully cooperate with CBI."
