OAK LAWN, Ill. -- Police in Oak Lawn say someone attached 10 screws to two slides in a local park in a deliberate attempt to hurt children.
No one was injured, but the screws could cut or rip the skin of a child playing on the slide.
Park officials took out the screws immediately, so the holes are all that's left behind at Memorial Park.
Each screw was placed at the bottom of a slide and officials are certain it was intentional.
Oak Lawn police stepped up patrols in the park Wednesday.
The thought that someone did this on purpose rattles parents.
"There were eight screws in one slide, two in the other slide. They screwed them into the bottom of the slide and snapped off the heads so there was a protrusion of metal,” said Joel Craig of the Oak Lawn Park District.
This isn't the first case of playground tampering in Illinois.
In March, a 2-year-old was injured after more than a dozen razor blades were glued to playground equipment in East Moline.
