(WWJ) Michigan police are investigating the discovery of more than 40 razor blades scattered around playgrounds in Eaton Rapids, just south of Lansing.
Police were called to Howe Park on Monday after a little boy found a razor on a slide.
When they arrived, officers found several more scattered in what they said were strategic locations around the park.
They appeared to be meant to cause harm, police said.
Officers checked another nearby park and said they found more blades scattered around the grass.
In response, all the city's parks were closed yesterday for inspection.
No injuries were reported.
Police have no information on any possible suspects or motive.
