This news article reports that senior leaders of the Pakistan Tehreek-e-Insaf (PTI) political party, including its chairman Imran Khan, were booked for attacking police and using foul language against national security institutions in Lahore. The incident occurred after Section 144 was imposed in the city and a mob of 300-400 committed violence and abused state institutions. The FIR was lodged under various sections of the Anti-Terrorism Act and Pakistan Penal Code. Clashes erupted between PTI workers and police in Lahore when the government banned Khan's planned rally to kick-start his election campaign. The government imposed Section 144 for seven days, and PTI workers attacked police when they were ordered to disperse. In retaliation, police used water cannons, tear gas, and batons to disperse them, injuring several people on both sides. Several workers were arrested, and PTI called off the rally after the clashes.
