The NAB had arrested the suspect a day before and produced him before the court on Thursday for his first remand.
A special prosecutor requested the court for 15-day physical remand of the suspect. He said the suspect used to transfer huge amount in the bank accounts of Shahbaz Sharif's sons Hamza Shahbaz, Suleman Shahbaz and other family members.
He said custody of the suspect was required for the procurement of evidence and recovery of crime proceeds. The court allowed the remand and directed the NAB to produce the suspect again on September 19. Three suspects namely Mushtaq Cheni, Aftam Mahmood and Shahid Rafiq turned approvers in the case against family of the opposition leader.
