ISLAMABAD, MAY 23: PTI Chairman Imran Khan on Tuesday spent nearly four hours at the National Accountability Bureau’s Rawalpindi office in connection with the probe in the Al-Qadir Trust case.

The case alleges that the former premier and his wife obtained billions of rupees and land worth hundreds of kanals from Bahria Town Ltd for legalising Rs50 billion, which was later identified and returned to the country by the UK during the tenure of the PTI government.

The PTI chief and his wife, Bushra Bibi, arrived at the NAB office a little after noon. Ahead of their arrival, security outside the bureau was tightened. While Imran was inside the accountability watchdog’s office, his wife waited outside in the former premier’s bullet-proof vehicle.
