ISLAMABAD - The joint investigation team - consisting investigators from FIA, police and banking sector - appointed by the National Accountability Bureau (NAB) is expected to begin probe into Arsalan-Malik Riaz case at the start of next month, sources said on Wednesday.On Tuesday, the Islamabad Police chief nominated its two officers – SP Faisal Memon and ASP Capt Mustansar - to join the joint investigation team to probe the ‘family gate’. Meanwhile, the Federal Investigation Agency (FIA) had already nominated Deputy Director Nasrullah Gondal to represent the agency in the team, sources said.The decision to constitute a joint investigation team to probe the much hyped ‘ family gate’, which shocked even those in the power corridors, was taken by NAB Chairman Admiral (r) Fasih Bokhari on June 15, following the directives from the Supreme Court which asked the later to investigate the matter.Complying with Supreme Court orders, the NAB asked the FIA and Islamabad Police last week to nominate their investigators to be inducted into the joint investigation team last week. Finally, Islamabad Police assigned the task to two well-reputed young officers, while Nasrullah Gondal will represent the FIA in the team.It is important to mention that Attorney General Irfan Qadir had sent a letter to NAB on June 14, asking it to constitute a joint investigation team to probe the Arsalan-Malik Riaz case.“It is true that the NAB has almost finalised the team with the help of law enforcement agencies which will start working shortly,” an NAB official told TheNation on Wednesday, while requesting not to be named.The Supreme Court on June 14 had directed the federal government to take action against the chief justice’s son, Arsalan Iftikhar, on merit if found guilty of the allegations levelled against him by the business tycoon.Fasih Bokhari’s close association with President Asif Ali Zardari and his relationship with Malik Riaz through his (Bokhari’s) daughter, who served Riaz as an employee of Bahria Town, raised several questions about the transparency in the probe. This newspaper reported on June 15 that the NAB chairman’s daughter, in an apparent attempt to bail out her father from the media onslaught over her job matter, resigned from a lucrative post in the Bahria Town. However, folks are still are doubtful that an inquiry, conducted by NAB with Fasih Bukhari in the chair, have any chances of being transparent.
