Investigative officer, Kamran Faisal, was residing in room no. 1 of Federal Lodges in Islamabad.The deceased, assistant Director of NAB’s Rawalpindi chapter, allegedly committed suicide by hanging himself to the ceiling fan.Immediately after the incident took place, NAB Chairman Fasih Bokhari, Inspector General of Islamabad Police Bani Amin and other officials of NAB and police reached the Federal Lodges and declared it to be a case of suicide, based on initial investigations.However, the real facts can only be unearthed after postmortem is done and medical report is issued.Faisal was a father of three, including a daughter. He belonged to Mian Channu in Punjab.He had assisted Deputy Director of NAB’s Rawalpindi chapter, Asghar Khan, in the inquest of RPP case.Sources said that Faisal was under pressure for some weeks because he and Khan had been suspended by the NAB when they forwarded the investigation report through Director General NAB Rawalpindi Col (retd) Subah Sadiq.The report was sent for approval from Bokhari for filing references against Prime Minister Raja Pervaiz Ashraf and 15 others named in the investigation before the Accountability Court in Rawalpindi.The NAB had also suspended Sadiq and attached him with NAB Headquarters in Islamabad. Sadiq has been replaced by DG NAB Lahore Khursheed Anwar Bhinder.The officials had been removed from the investigation of the RPP cases by Bokhari, saying that the Supreme Court of Pakistan was happy with their performance in the case.More than 20 officials of NAB from Punjab while talking to The Express Tribune alleged that it was murder which was being framed as suicide, because the roof window of Faisal’s room was ajar when the police went there for investigation.Earlier last year, the court directed NAB to proceed against all government functionaries involved, including the ministers for water and power during whose tenure the RPP were approved or set up, and the minister and finance secretary holding charge when down payment for RPP was increased from 7% to 14%.Liaquat Jatoi and Prime Minister Raja Pervaiz Ashraf were water and power ministers in 2006 and 2008, respectively, while Shaukat Tareen was the finance minister in 2008, when down payment was increased.Of the 19 RPP deals signed initially, only nine were allowed to function after a damning Asian Development Bank evaluation report. Subsequently, six of those nine RPP were discontinued.
