A mother and son unwittingly discovered a 2-inch mortar whilst magnet fishing in Helmsley, North Yorkshire. Unaware what the device was, they took it home with them to Hull.
It was only later that they realised the potentially significant nature of their find. After calling the Police, an Explosive Ordnance Disposal (EOD) team was mobilised from Catterick to remove the mortar for safe disposal.
