The PTI leadership has directed its workers to demonstrate against Khan's arrest, and an "emergency committee" that was established in the event of his arrest will soon make clear what will happen next.
After this, PTI workers staged violent demonstrations in a number of cities, including Islamabad, Rawalpindi, Lahore, Karachi, Gujranwala, Faisalabad, Multan, Peshawar, and Mardan.
Protesters and police engaged in physical altercations near the nursery area on Sharea Faisal in Karachi. The PTI workers destroyed a bus, tore down street lights, and flung stones at and set fire to police cars. According to reports, police shot tear gas rounds at the demonstrators.
Other cities where protests took place also saw public property damaged, including Rawalpindi and Lahore.
Zaidi was released from jail on bond just days before his arrest after reaching an "out-of-court settlement" with the complainant in a fraud case.
At least 23 PTI workers have also been detained as a result of the demonstrations at Sharea Faisal.
