Disgusted residents in Swinton have contacted the police after someone left metal nails sticking up from the ground in a grassy area used by children to walk to school.
One resident, who asked to remain anonymous, said she spotted the nails for the first time on January 26 in a communal garden, directly across from the popular local Moorside Park.
The mystery stranger who left the nails also appeared to have also planted a sign nearby which reads: "If you ride on the grass you may fall into a trap!! Beware!"
