The graft case involving a former president of the National Bank and 13 others accused in corruption of over Rs 21 billion, is moving in a snail pace, investigation official said in the court here on Monday. According to the investigation officer, one year had passed since the statement recorded by a witness in the case. The counsels of the accused get the date of the next hearing on the proceeding of the case every time, he said. Former National Bank of Pakistan president Ali Raza and other officials are facing the allegations of graft during 2003 to 2008 at the NBP branch in Dhaka, Bangladesh. The Investigation officer claimed that the accused were also involved in corruption in the bank welfare fund. The irregularities were revealed in audit report of 2009. In September 2017, National Accountability Bureau (NAB) had arrested the ex-NBP chief on charges of corruption after the Sindh High Court turned down his bail request.
