An Army technical officer went to the scene and confirmed it was a live WW1 "Mills Bomb" hand grenade.

The Mills bomb grenade was first developed during World War One in 1915, and became the first hand grenade to be issued on a large scale in Britain.

Among the five live ordnance items found were a British “Mills Bomb” grenade from World War II, a Navy 37-millimeter steel artillery shell from World War I and a post-WWII 20-millimeter shell for an Oerlikon anti-aircraft gun, officials said.

The bomb they used was the Mills bomb which had been adopted for general use in the British army.
