澳大利亚一名11岁的女生带着一枚手雷参加班里的展示讲解活动，结果导致全校450名学生和60名教师紧急疏散。这枚手雷没有引爆栓，经弹药专家检测后认定可能是一枚来自一战时期的废弃手雷。据女生家人介绍，这枚手雷是几周前一位朋友带至家中的，大家都认为是仿造品，才会让女孩带到学校展示。学校老师见到女孩带来的手雷后，立即将其上交给校长并疏散了全校师生，同时报警处理。校方表示，这名女生不会受到任何惩罚。

A school in Australia has been evacuated after an 11-year-old girl brought a hand grenade to show-and-tell.

A police bomb squad removed the device and cordoned off the area around the school after the girl turned up at a morning class with the grenade, which did not have a pin.

Police said the girl's family received the grenade from a friend several weeks ago and thought it was a dummy. The grenade has been taken for examination by Defence Force munitions experts but is believed to have been an inactive device, possibly from World War I.

The school's 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.

"I wasn't sure if it was a dummy and I didn't want to take that chance," he said.

Mr Allen, from the Hunter Christian School in Newcastle, said the girl would not be punished.

"She's bewildered, embarrassed – I tried to make her aware she's not in trouble,'' he said.

"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. It was heavy, but I assume practice grenades would weigh that much too."

Police said the device had been inspected by Defence Force experts, who took it for testing and would probably destroy it.

"There's no doubt that it did pose a potential threat and the actions we've had today are appropriate in the circumstances," said Police Inspector Gerard Lawson."In a classroom, certainly if it was live and it was a fully functioning device it would cause serious injuries to all the occupants."
