Police and city crews in Oakville, Ont. searched a playground on Monday for razor blades after several were found late last week.
Halton Region police say at least seven razor blades were found in Munn's Creek Park, which is located close to River Oaks Public School.
Three blades were found on April 4 by a woman who was visiting the park. She called Oakville's city hall. Municipal workers using magnets and metal detectors found more over the weekend.
"It's very bad for them to do it because we like playing at the park," one young girl told CTV's Janice Golding.
All the blades were found near playground equipment, according to police Sgt. Murray Drinkwalter. But police do not know how the razors got there or why someone would do it.
"They're found in such a manner where they're underneath the mulch that forms the basis of the playground," Drinkwalter said.
"Our investigation indicates that the razor blades have been there for some time. They are quite rusted."
Other playgrounds in the area were searched but no razors were found. Officials expect that Munn's Creek Park will remain closed until Tuesday.
Last week, the principal of River Oaks school sent a letter home to parents. That message led to another discovery.
"As a result of that letter going home, a Grade 8 student approached the vice-principal and indicated ... that he had found a bunch of razor blades in the mulch during March Break," Drinkwalter said.
Oakville parents are upset and bewildered by the discovery.
"You feel like it's safe just to send them across the street to go to a park and play, so it is a concern," one father said Monday.
"When you can't take your kids to the park to play, where else is there that you can go," a mother asked.
"It's scary. Anytime anything like this happens it's shocking, and it happens in other places it seems all the time, but not close to home and not right across the street from where you live," added another father.
Police are confident there are no more razor blades at the park.
Similar incidents have happened in the Greater Toronto Area in the past. Last November five razor blades were found in an Etobicoke playground.
More than two years ago, 13 razor blades were found in pieces of wood placed under the sand of Toronto's Woodbine Beach.
Shortly after that, someone glued broken glass to playground equipment in Burlington.
