Parents are worried after police in Texas found multiple razor blades melted into slides at local parks.
KHOU reports city workers found 4 razor blades on two slides at parks in Huntsville, a city just north of Houston.
Investigators says lighters were used to melt the blades into the plastic slides so they would be less conspicuous.
City workers were able to remove the razor blades before anyone was hurt, but parents are worried for their children.
"This should be a safe haven for children, they should be able to be playing, be normal children," Roosevelt Dancey, a father, told the station.
Cameras have been installed nearby other parks in an attempt to catch whoever is responsible for placing the razor blades in the playgrounds.
