In a rather bizarre incident three people including two police constables were injured when a grenade went-off inside an Anti-Terrorism Court in Pakistan's Karachi. The mishap occurred when a police constable was demonstrating the working of the grenade which was recovered as evidence in a case. Apparently the policeman did the live demo of the undefused grenade at the request of the judge. which explaining the working of the explosive device, he pulled the pin-off the grenade. This resulted in a loud explosion, injuring three including the constable, a court clerk and throwing the judge off his chair. Let us just hope that with his first hand experience now, the judge won't ask for a demonstration the next time something similar come in front him.
