Khan, the leader of the opposition Tehreek-e-Insaf party (PTI), was taken into custody on Tuesday, following a hearing of the Islamabad High Court in connection with corruption involving the Al-Qadir Trust, which he heads with his wife. The politician is facing an inquiry in the case related to a settlement between the PTI government and a property tycoon, which reportedly caused a loss of 50 billion Pakistani rupees ($17.6 million) to the national exchequer.
