Police were called to a building site by the Gatwick South Terminal at 10.50am (Thursday October 13). A cordon was quickly set up before the Military Ordnance Disposal (EOD) team arrived. Five potentially deadly World War II devices were identified - three hand grenades, one four inch mortar and a smoke grenade. Police say the weapons ‘had apparently been unearthed over recent weeks and stored in a metal container before police were called today’. The EOD team carried out a controlled explosion on all the objects at 1.20pm. Air and train arrivals and departures - including Southern Rail - were suspended for 15 minutes as a precaution when the explosion took place. A spokesperson for Sussex Police said: “There was no damage or injury and the incident is now closed.”
