The dangerous trap was found in a park in Swinton, a town in the City of Salford in Greater Manchester. The horrified residents have contacted the police in fear that the nails may cause serious harm to a child in the area.
One resident, who asked to remain anonymous, said she spotted the nails for the first time on Wednesday afternoon, January 26, as reported by the Manchester Evening News.
The area is a communal garden belonging to those who live in the flats and sits directly across from the popular Moorside Park.
Disturbingly, the nails were accompanied by a cryptic warning message.
The mystery stranger who left the nails appears to also be responsible for a sign which reads: “If you ride on the grass you may fall into a trap!! Beware!”
One resident who lives nearby with her daughter, said of one: “It’s a 12 inch full-on metal nail sticking out of the ground. It’s horrible.
“My little girl loves to run around near there.
“All it takes is a kid to run through and trip and they could die from something like that.”
She added: “There’s a few ways you can walk to the local schools with kids and that’s one. It’s directly across from Moorside Park.
