An Explosive Ordnance Disposal (EOD) team was called to a property in Surbiton after a resident found a 1kg German incendiary bomb in the garden.
The device – of a type which were dropped in their hundreds of thousands during WWII by the Luftwaffe – was uncovered amongst flowerbeds, presumably having laid in situ for more than 75 years.
Unlike high explosive bombs that were designed to cause blast damage, the job of incendiary bombs was to cause large conflagrations, which not only caused damage and disruption but lit up wide areas for following bomber aircraft to drop their heavier payloads.
The EOD team were able to remove the device without any further action.
