A former senior superintendent of police (SSP), whose son has allegedly been held in illegal confinement by SSP Rao Anwar, on Wednesday moved a constitutional petition in the Sindh High Court (SHC) seeking an inquiry and registration of case by the National Accountability Bureau (NAB) against Anwar for allegedly laundering Rs85 billion from Pakistan to other countries.

Ex-SSP Niaz Khoso, represented by Advocate Rashid A. Razvi, alleged in his petition that Anwar had amassed substantial wealth through illegal and corrupt practices, including land grabbing and money laundering, as SSP Malir over the past nine years.

He also questioned how SSP Anwar had managed to remain posted at the Airport police station since 1984.

"He has always chosen to be an officer at Airport police station since he was assistant sub-inspector, sub-inspector and Inspector," the former SSP said.

The petitioner said that even when Anwar was promoted to the rank of SP, he again chose to be posted as SSP Malir.

He also asked how, when SSP Anwar's declared monthly income was about Rs70,000, he had 'acquired' House No 133 in F-10/4, Islamabad, whose worth was "well over Rs500 million".

Ex-SSP Khosa also accused SSP Anwar of being involved in money laundering and travelling abroad extensively.

He also provided a 'travel record' for the SSP, claiming that Anwar had travelled abroad 89 times from Karachi's Jinnah International Airport between May 2012 to Feb 2017.

The petitioner requested the court to direct the chairman and director general of NAB to authorise an inquiry into the 'corruption' of SSP Anwar and others under Section 9 of the NAB Ordinance 1999.

He also requested the court to direct the Interior Ministry to place SSP Rao Anwar's name on the Exit Control List "as he has his assets in the United Kingdom and Dubai and may try to flee the investigation".

The petitioner named the interior secretary, NAB, DG NAB Sindh, the Federal Investigation Agency and the provincial police chief as respondents in the case.

The petition will be taken up for a preliminary hearing by a division bench of the high court on Thursday.
