A three-year-old boy, on an Easter egg hunt Saturday morning, discovered a live hand grenade (photo). The device was on the side of a busy road, next to the field where families were conducting their Easter ritual in Holford in Somerset, England.
According to reports in the British press, the boy was actually standing on the device when an adult spotted him.
"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 the Daily Mail. " I was shocked. The boy who was standing on it thought it was a rock." Moffatt is an engineering consultant who was attending the event with his wife and their three young children.
About 25 children were reportedly in that field on the Easter egg hunt. This is Somerset reported that the device was destroyed in a controlled explosion:

A controlled explosion destroyed a suspected hand grenade found during a children's Easter Egg Hunt in Somerset yesterday.
One of the families taking part in the Easter hunt at Holford, near Bridgwater, raised the alarm yesterday morning after discovering what appeared to be a grenade by the side of the road.
​Part of the A39 was closed while the police cordon was in place
Police were quickly joined by explosives experts at the scene, and a hundred meter cordon was immediately put in place. Part of the A39 was also closed as part of the safety precautions. The road was later reopened to traffic with a cordon remaining in place, but that was taken down late yesterday afternoon after an Explosives Ordnance Disposal team carried out a controlled explosion.
An Avon and Somerset Police spokesman said: "The EOD has attended the scene and destroyed the object in a controlled explosion. The cordon has been lifted and the local community are thanked for their patience while this incident was dealt with."
The affected stretch of the A39 was between Netherstowey and Kilve. Holiday traffic and heavy vehicles were diverted along the A358, while other diversions were put in place for local traffic.
On the earlier road closure, Inspector Mike Ashwin said: "Closing the road is not a decision we have taken lightly but public safety is always our primary concern with incidents such as these. I appreciate this will cause disruption to motorists especially over the holiday weekend and I would ask for patience while we deal with this incident. Drivers are advised to avoid the area, leave extra time for their journey and follow the diversions which are in place."
The road was reopened to traffic shortly before 1pm yesterday afternoon. 

The Mail says the grenade is believed to have been a relic from World War Two.
