According to videos circulating on social media, Khan was sitting in the diary section of the high court to get his biometric verification done, when armed Rangers personnel forcibly entered the room and took him away. At least fifty uniformed personnel in riot gear could be seen surrounding the former premier as they forced him to enter a black vehicle with signals jamming equipment installed on it.
Inspector General of Police (IGP) Islamabad Dr. Akbar Nasir Khan confirmed the arrest and stated that "the situation is under control". NAB officials had warrants for his arrest, the IGP added.
While expressing concern over the unexpected arrest, IHC chief justice Amir Farooqi said that they should be informed in what case Imran Khan has been arrested. "Whatever happened on the court premises caused a law and order situation," he added.
