"Islamabad: Former Foreign Minister of Pakistan and Vice Chairman PTI Shah Mahmood Qureshi Arrested," the party said on social media.
The 67-year-old, who served as foreign minister under Khan until his ouster in a no-confidence vote last year, was taken into police custody shortly after giving a press conference, in which he defended Khan, who is likewise under arrest, the party said.
Pakistani TV reported that federal agents arrested Qureshi at his residence as part of an ongoing investigation into a leaked Pakistani diplomatic cable that exposed US role in Khan's removal from power.
In October 2022, Pakistan's election commission stripped Khan of his parliamentary mandate as well as the right to be elected and appointed to both the country's federal and regional legislatures for five years, after finding him guilty of selling 52 valuables stored in the Toshakhana, Pakistan's national treasury, and concealing information about gifts he received personally. In April 2022, then-opposition leader and current Prime Minister Nawaz Sharif said Khan had sold state treasures in Dubai worth a total of 140 million Pakistani rupees ($500,000).
In early August, an Islamabad court sentenced Khan to three years in prison after finding him guilty of corrupt practices in the Toshakhana case.
