This was stated in a report submitted by the corruption watchdog in an accountability court.
According to the report, Kamran Iftikhar Lari is willing to return the amount he allegedly embezzled. He moved a plea, offering to return Rs1.39 billion in three instalments.
The bureau accepted his plea bargain, the report said.
The NAB had named former PSO chief Naeem Yahya Mir, former general manager (supply) Akhtar Zameer, a former director of the ministry of petroleum and natural resources, and others in the reference. The reference said the accused indulged in corrupt practices, causing losses worth Rs23bn to the national exchequer.
