An army bomb squad rushed to a school that was evacuated after a pupil brought a hand grenade to a history class.
Children at Parkside Community School, in Chesterfield, Derbyshire, were ordered out of the building while police brought in an army explosives team to take a look at the grenade.
Skilled technicians from the bomb squad arrived at the scene and examined the grenade at around 11am on Wednesday.
It turned out to be only a scare fortunately as the grenade had been decommissioned.
It is believed that the grenade had been brought in by a Year 7 pupil.
After the bomb squad gave the all-clear, the children were allowed back into the school and carry on with their classes.
A police spokesperson said: “We were called at 11am today by the school as a student had brought an old hand grenade into a history lesson.
“Part of the school was evacuated while the military EOD (Explosive Ordnance Disposal) team was contacted.
“The team attended and examined the item, confirming it had been decommissioned.”
