Violence erupted across Pakistan on May 9 when cricketer-turned-politician Khan was arrested by the National Accountability Board (NAB) from the premises of Islamabad High Court in a corruption case. Khan was released on bail two days later.

Over 20 military installations and government buildings including military headquarters in Rawalpindi were damaged during the May 9 mayhem that has been termed as the "Black Day" in the history of Pakistan.

Over 100 vehicles of police and other security agencies were also set on fire during the violence that left more than 10 persons dead.

Khan, however, said over 25 PTI workers were killed in the violence and that law enforcement agencies arrested over 10,000 PTI workers across Pakistan. As many as 4,000 of them are from Punjab.
