Imran Khan, the former prime minister of Pakistan and leader of the Pakistan-Tehreek-e-Insaf (PTI) party, has been implicated in six cases, three of which fall under the stringent Anti-Terrorism Act, in connection with the unprecedented assault on the General Headquarters (GHQ) of the army in Rawalpindi on May 9. The attack, dubbed a "Black Day" by the military, saw supporters of Khan breach the gates of the GHQ, leading to a series of investigations by joint investigation teams (JITs) into various incidents of violence, including the targeting of military installations and an arson attack at a metro station.
