Right after assuring courtroom attendees that the grenade had been diffused, he pulled the pin—and the grenade exploded.
The policeman, Constable Liquat Ali, was in Karachi’s Anti-Terrorism Court, trying to counter an argument that a grenade was too difficult for a defendant to use—then demonstrated the simplicity of removing the pin, according to court officials.
Ali's hands were injured from the blast, along with a court assistant and one other policeman.
