A top officer of Pakistan's top investigative agency who was probing the PKR 14 billion money laundering charges against the joint Opposition's prime ministerial candidate Shehbaz Sharif has gone on leave for indefinite period after Imran Khan was voted out in a no-confidence motion.

Federal Investigation Agency's Lahore chief Mohammad Rizwan's application to go on leave with effect from April 11, 2022, onward, has been accepted, according to an official notification on Sunday.

Rizwan's decision came a day before Shehbaz and his son Hamza are to appear before a special court for indictment on Monday.

The special court (Central-I) of FIA on April 4 had summoned Shehbaz and Hamza on Monday (April 11) to indict the father and son duo in the Rs 14 billion money laundering case.
