ISLAMABAD: A preliminary post mortem report over the death of Kamran Faisal, an officer of the National Accountability Bureau (NAB) investigating the rental power projects (RPP) case, has stated suicide as the apparent cause of his death, DawnNews reported.

The report, released by a board comprising three doctors at the Poly Clinic Hospital on Saturday, added that no torture marks had been found on Faisal's body.

The report added that there was only one mark on Faisal's neck and it appeared that he had committed suicide.

Sources told DawnNews that samples had been sent to a forensic laboratory in Lahore for further examination.

The laboratory is expected to send the forensic report in seven to 10 days' time after which a final report would be released.

The preliminary report had been submitted in the Islamabad Secretariat Police Station.

Sources had earlier told DawnNews that the police had declared Faisal’s death as accidental and a First Information Report (FIR) was also registered.

Separately, some of Faisal’s relatives have alleged that his body bore marks of torture. His uncle has said that Faisal’s back, arms and wrists showed torture marks.

A special police team has also left for Faisal’s ancestral town to collect information from and record the statements of his family members and relatives.

Police is also reportedly looking for Sajid Ali, a close associate of Faisal, but has so far failed in getting in touch with him.

Faisal, 35, who was investigating the scam along with another officer Asghar Khan, was found hanging from a ceiling fan in his official residence at Federal Lodges.

Faisal was reportedly investigating the scam under ‘pressure’ and had recently requested the Supreme Court to exclude him from the case.
