A dad and his two sons stumbled on a smoking WWII bomb during a morning stroll at the beach.
Oliver Tanton Brown, 40, was telling his sons Sammy, eight, and Jacob, five, about the weird and wonderful things that can wash up on the shore when they discovered the unexploded bomb.
The quick thinking trio were praised for alerting coastguards who sent a bomb squad to detonate the weapon at Warren Beach in Folkestone, Kent.
The family, from Hythe, had been crabbing by the warren on Friday when they spotted the wartime relic and soon realised it was a smoking bomb.
When little Jacob noticed smoke coming from the mysterious object, Oliver took the boys back to the car and called the coastguard.
The businessman, who owns Eco Rocks, said: “It was our last day before the boys go back to school so we went for a wander, did some crabbing and ended up finding that.
“The boys wanted to go to the warren and I was trying to make the walk a bit more exciting for them by telling them how you can sometimes find old relics down there when we stumbled upon it.
“There was dust coming out of it and I realised it could be quite dangerous so then I moved it away and called the coast guard.”
Oliver directed the bomb squad by phone and the device was identified as a WWII phosphorus mortar.
Coastguards cordoned off the area to keep people at a safe distance while the weapon was safely detonated in a controlled explosion.
White phosphorus is a dangerous chemical which is often used for naval flares and is capable of causing serious burns.
Oliver and his two boys were praised for their good judgement and the dad-of-two said it was definitely a day they would not forget.
A spokesman from the Maritime and Coastguard Agency said: “The person who found it did exactly the right thing by calling it in to us.
“We’d rather it were called in and turn out not to be harmful that the other way around.”
Footage shows the bomb being detonated in a controlled explosion before it was safely disposed of.
An MOD spokesperson said: “An Army EOD Team were called out to East Wear Bay to assist HM Coastguard with the routine disposal of ordnance.
“The device was rendered safe by means of a controlled explosion, and recovered for subsequent safe disposal.
“Military personnel are regularly required to assist with the disposal of historic ordnance such as this, ensuring every situation is dealt with as quickly as possible for the safety of the general public.”
