An area of Kettering was taped off yesterday (Tuesday) after a couple who were metal detecting found what they believed to be a grenade.
Police were called to Cheyne Walk just before 5.30pm after the pair’s find by the nearby River Ise.
A 50m cordon was placed around the area before the EOD (Explosive Ordnance Dispoal) arrived and made the device safe.
A Northamptonshire Police spokesman was unable to confirm whether the device was live.
The scene was closed down at 7.40pm.
