National Accountability Bureau (NAB) on Sunday summoned former railways minister Khawaja Saad Rafique and his brother Khawaja Salman Rafique on August 15.

Sources privy to anti-graft watchdog revealed that the Khawaja brothers have been summoned in relation with the Paragon City case. The bureau has also directed Khawaja brothers to bring the complete record of the project with them.

NAB has reportedly found documents establishing Khawaja Saad Rafique and his brother Khawaja Salman Rafique’s link to the Paragon City in Lahore.

A transfer deed of over 50 kanals bearing names of the Khawaja brothers and Paragon City chief executive officer surfaced on Tuesday. According to documents, the two also acquired land in Paragon City.

The railways minister had earlier claimed that he had no link with the Paragon City.
