Magnet fishers discover 19th century Royal Navy cannon in river

A group of magnet fishers were left stunned after pulling a Royal Navy CANNON dating back to the 19th Century out of a river - in one of the first discoveries of its kind.

Six members of The Peaky Dippers spent several hours scouring the River Don, in Sheffield, after hearing stories about wartime artillery being dumped there.

And they were left gobsmacked when they latched on to a heavy item while fishing from the riverbank - and hauled out a 3ft (0.9m) antique cannon.

The treasure hunting group, based in Birmingham, later discovered it belonged to the Royal Navy Signals and dated back to the 1800s.
