A man wielding a gun was arrested from outside the Parliament House in Islamabad on Monday.
Footage shows the man walking on the main road, waving a pistol in one hand and what seemed like a knife in the other. Several security officials appeared to surround him.
Police said the arrested man was shifted to Secretariat Police Station and a pistol was confiscated from him.
After arresting the suspect, police said the initial investigation revealed he is a 45-year-old man who lives in Rawalpindi’s Chakri area.
Police say the suspect is suffering from mental illness.
Interior Minister Sheikh Rashid Ahmed said during a press conference that the weapon confiscated from the man had no bullets inside.
