Pakistan Tehreek-e-Insaf (PTI) leader Sher Afzal Marwat was briefly detained by Islamabad police on Thursday during a scheduled rally in Tarnol. A heavy police presence arrested Marwat as he and other party workers arrived at the site. Earlier, PTI postponed its Islamabad power show after the city administration canceled the No Objection Certificate (NOC) for the public gathering scheduled in Tarnol on the same day.
