“Police swooped on a boy's eighth birthday party after bangs from plastic toy Nerf guns were mistaken for real gunfire. The officers were deployed after a neighbour reported the sound of children screaming in the quiet village of Yaxham, Norfolk. But moments after arriving they found Oliver Green celebrating his birthday by shooting the soft brightly-coloured bullets with his friends in the toy gun battle. And when police asked what was happened, Oliver told them: 'I am the birthday boy officer, but I am not sure what I have done wrong.”
