A family called in Thames Valley Police after they discovered a live hand grenade when moving house.
With the help of the Army's Royal Logistic Corps (RLC) Bomb Disposal, the munition was identified as a live Mills Bomb No 36, dating back to the Second World War.
The British hand grenade had been handed down over the years by relatives and was disposed of in a safe manner.
According to the bomb disposal team, this type of munition find is not uncommon.
In the event of such a discovery, the team advises members of the public to ring 999 and assume anything which presents as an explosive device or a suspicious package is live and dangerous until verified otherwise by experts.
