CBI sources said Patnaik's letter was found during a probe into the alleged irregularities in allocation of coal block -- Talabira II -- to Hindalco. This coal field was meant for Public Sector Undertakings.
CBI said while no final decision has been taken as to who all would be questioned, the sources said the Chief Minister may be examined only if a need was felt to seek his views on the reasons for recommending coal blocks to Hindalco.
CBI Director Ranjit Sinha said the case was being monitored by the Supreme Court. "We are providing all the details to the apex court in our status report to be filed later this month," he told reporters here.
He denied that the filing of FIR had anything to do with the timing. "We registered the First Information Report on the basis of available material during the preliminary enquiry. Further evidence would be gathered during further probe," he said.
