An 11-year-old girl brought a hand grenade to her class in an Australian school for a 'show and tell' activity today, prompting evacuation of over 500 students and teachers.
Police were called to Hunter Christian School in Sydney after a teacher discovered the girl had brought a "pineapple" hand grenade, a model of weapon used in World War-II and the Vietnam War.
Some 450 students and 60 teachers of the school were evacuated to a park near the school and allowed back after the New South Wales Police Bomb and Rescue Unit declared the school safe.
Police said they believed the grenade was inactive but Australian Defence Force personnel took away the device with them to examine it, local media reported.
Police Inspector Gerrard Lawson said authorities wanted to reassure parents that all students were safe. "At this time we anticipate an early resolution to this issue but we will await specialist advice as to the safety of moving the item," he said.
The girl "understood it to be a dummy hand grenade that had been deactivated, there was no firing pin, just the body of the grenade,"u00a0
