An Explosive Ordnance Disposal (EOD) team was rushed to Bromley in London after the discovery of a suspect device in a garden shed.
Amidst the cobwebs they found a WWII-era German incendiary bomb. These were dropped in their hundreds of thousands by the Luftwaffe during the Blitz, designed to start fires with their incendiary content rather than cause destruction through high explosive.
Presumably collected as a souvenir, the inert bomb was taken away for safe disposal.
