A 3-year-old boy was busy on his Easter egg hunt when instead of an Easter egg, he discovered a live hand grenade.

The boy was standing on the explosive, when someone recognized the object. “We were beginning to count up the eggs at the end of the hunt and I saw a boy of three standing on an object. ‘It was brown and about four inches high. It looked like an Easter egg, but it was a hand grenade,” Stuart Moffatt told reporters. ” I was shocked. The boy who was standing on it thought it was a rock.”

The grenade is believed to be an old relic from WWII. It was destroyed in a controlled explosion.
