Pakistan Muslim League-Nawaz (PML-N) leader Khawaja Saad Rafique and his brother Khawaja Salman Rafique on Wednesday have been produced before accountability court in Paragon Housing reference.

On the occasion, stringent security arrangements have been taken to avoid any untoward incident.

On April 26, the NAB Lahore had approved filing of a reference against the Khawaja brothers and Nadeem Zia for the alleged corruption.

Qaiser Amin Butt, the main accused in the case, was also included in the inquiry initiated by the NAB, and arrested in November last year. Later, he agreed to turn approver against the Khawaja brothers and Zia.

On December 11, 2018, Khawaja brothers were detained by the accountability watchdog after the Lahore High Court (LHC) rejected their bail plea.
