He was taken into custody from the court premises by paramilitary forces. Leaders from Pakistan-Tehreek-e-Insaf (PTI), have alleged that the police entered the court and dragged him outside.

The arrest comes a day after the country's powerful army had accused Imran Khan of levelling baseless allegations against a senior officer of the spy agency ISI.
