“East Moline parks are safe, but it’s just a bad situation,” Foltz said. “Maybe a group of kids … figured this would be a fun prank to do.”

Ty Langley, a parent in East Moline, told KWQC he was worried because “You don’t really think about razor blades.”

“We just kind of think about them swinging on the swing set or, you know, climbing the monkey bars,” Langley said. “It’s something I can look out for now.” Police checked all city parks late Wednesday and “have not found anything else in any of the parks,” Foltz said.
