A primary school was forced to evacuate staff and children and call in bomb disposal experts after a pupil brought a hand grenade to a show-and-tell assembly.
The youngster unexpectedly produced the WW2 explosive device at Osmaston CofE Primary School in Ashbourne, Derbyshire - causing shock among staff.
Head teacher Jeanette Hart said she was 'unsure if the grenade was live' - so took it from the boy and placed it behind a 'substantial' tree in the school's car park while the emergency services were called.
Army experts later established the grenade was safe, but police praised the 'quick-thinking' staff.
Mrs Hart said: 'It was quite an eventful assembly. It was going fine and there was a boy who brought an old bullet case in, which I knew about, but then his friend produced a hand grenade from his pocket. That, I was not expecting.'
