Before police arrived, citizens had already found 39 razor blades, and city staff and police found two more in the park. They told police some of the blades appeared to have been placed intentionally to cause harm.
Witnesses said two men and two women, believed to be 17 or 18 years old, were on the playground before the blades were found.
City workers then searched other parks in the city out of an abundance of caution and more blades were found at Grand Army of the Republic Island Park in the grass.
