A judge in Pakistan asked a police constable to explain how a hand grenade works but instead of using words, he pulled the pin, causing it to explode.
The explosion inside Karachi’s Anti-Terrorism Court injured five people including the judge, the constable and a court clerk.
According to reports, the grenade was brought into court by officer Abid Ali as evidence. But it had not been defused, authorities said.
The constable will be disciplined after he recovers from his injuries, officials said.
The detonation prompted a high security alert by authorities who initially thought it was a terrorist attack.
