Boys fishing find WW2 hand grenade in river

The Mills bomb was first developed during World War One

A live World War Two-era hand grenade had to be detonated after being found by two boys out fishing at a river.

The discovery of the Mills bomb was made in Abercych, Pembrokeshire, on 13 July.

"The device was found to be live and in a dangerous condition which necessitated it being detonated at scene by controlled explosion," Dyed-Powys Police said.

The force said the boys "did the right thing" by calling emergency services, urging anyone who finds anything suspicious not to handle it and to contact emergency services.

The Mills Bomb is a classic pineapple-shaped hand grenade with a pull-pin and lever, first developed by Sir William Mills during World War One.

Later improved versions were used extensively during World War Two, and they remained in service for many decades after.
