A mother and son got a bit of a surprise when they went on a fishing trip together on Mother's Day.
The son's magnet fishing in Helmsley, North Yorkshire, brought up an unusual-looking rusty object.
It was at first believed to part of an old camping stove or farm machinery and transported home to north Hull.
It was only on Monday when suspicions grew about the object that the police were contacted, reports Hull Live.
The British Army's Royal Logistic Corps bomb disposal squad were then called up and after examining the object, identified it as a British practice mortar shell.
Fortunately, it was disposed of with no harm coming to anyone.
The grandmother of the bomb discoverer got in touch with Hull Live to share the story.
She said: "My daughter contacted me last night to tell me the bomb squad was on their way from Catterick after she contacted the police about something my grandson had found whilst magnet fishing in Helmsley on Mother’s Day.
"At first they thought it might be part of an old camping stove or farm machinery, it turned out to be an unexploded ww2 mortar bomb.
"This will be one Mother’s Day outing and treat she won’t forget.
"The army disposal x-rayed it and took it away, said it was a practice mortar apparently."
The police reportedly identified the object as possible ordnance and sent a picture to the bomb disposal squad at Catterick.
A Humberside Police spokeswoman confirmed the officer call-out on Monday evening to north Hull "following reports that a suspected WW2 explosive device had been found".
"The Explosive Ordnance Disposal Team attended and safely removed the device from the property."
