Families have found two deadly piranhas in a Yorkshire lake where children often paddle and ducks and fish have recently gone missing.
The carnivorous fish, known for their rows of sharp teeth, are normally found in the waters of the River Amazon.
But local residents have been left shocked after finding them in Martinwells Lake near Doncaster, south Yorkshire.
It is thought the fish may have been pets, which a owner then released into the waters when they got too big.

Locals fear the piranhas could be behind the disappearance of fish and ducks from the lake
Mother Toni Hooper, 32, from Doncaster, saw the fish when out walking with her family on Sunday.
She said: 'When we realised what it was it sent shivers down my spine. This is a popular spot amongst families, dog walkers and fishermen. It's always busy here.

The former clay pit is now home to a lake which is usually well-stocked with carp, tench, bream, perch, roach, pike and chubb along with usual pond life of newts, frogs and toads.
Ducks, coots and water hens all live on the pond which is visited each year by swans to raise their young.
Another walker, mother-of-three Lisa Holmes, 37, who was there with partner, tree surgeon Davey White, 37, and their youngest child, Sonny, eight, were shocked to find the razor-toothed fish.
Carer Lisa, from Doncaster, said: 'My partner is a fisherman and was looking around the edge of the lake when he suddenly spotted this fish floating near one of the pegs [fishing platform].
'He managed to get it out of the water and although he's a keen angler, he wasn't sure what type of fish it was straight away.
'But then we started looking at it more
