The latest development comes a day after the National Accountability Bureau arrested Pervez Elahi in the garrison city of Rawalpindi after his one-month detention expired. Elahi was detained under a law that allows the government to arrest any suspect to ensure law and order in the country.
Elahi is the president of Pakistan Tehreek-e-Insaf (PTI). Khan, who is imprisoned, is the chairman. Khan was arrested on August 6 after a court sentenced him to three years for corruption.
Tuesday’s development was a blow to former PM Khan’s party as Elahi was expected to campaign for his release. It came hours after police arrested Khan’s nephew, Hassan Niazi, on charges of inciting people to violence in May when Khan’s supporters attacked government and military installations.
