An Australian school had to be evacuated after an 11-year-old girl took a hand grenade to a show-and-tell.
A police bomb squad removed the device and cordoned off the area around the Hunter Christian School in Newcastle, New South Wales.
Police said the girl's family thought the grenade, which did not have a pin, was a dummy, reports the Daily Telegraph.
Headmaster Boyd Allen said the girl's teacher brought the grenade to him and he immediately evacuated the 450 students and 60 teachers and called the police.
He added that the girl would not be punished: "She's bewildered, embarrassed - I tried to make her aware she's not in trouble.
"She's a sweet young lady from a lovely family. She understood it to be a dummy hand grenade that had been deactivated, there was no firing pin, just the body of the grenade."
Police said the device, believed to be from the First World War, was being inspected by Defence Force experts, who would probably destroy it.
