Building works were stopped on a site in Hanwell, London after the discovery of a piece of Unexploded Ordnance (UXO) suspected to date from World War Two (WWII). The exact nature of the device has not been confirmed but, after the site was evacuated, it was swiftly removed by an Explosive Ordnance Disposal (EOD) team.
Despite being a predominantly residential area, Hanwell was regularly bombed during the Blitz in WWII. Several Heavy Anti-Aircraft (HAA) batteries were also located in the area, with unexploded shells often causing more of a menace than the German bombs!
