Shards of broken glass were placed at playground equipment in Dale Meadows Park last week.
On Wednesday, Summerland RCMP were called after a resident noticed broken glass had been placed on a slide and on the grounds nearby.
Municipal crews quickly attended to clean up the glass.
Sgt. Stephane Lacroix of the Summerland RCMP detachment said the glass had been placed deliberately.
He said it could have resulted in a serious injury if children had been out playing.
In summer, the playground equipment is used often.
After police examined the scene, they checked other playgrounds around the community, but did not find broken glass elsewhere.
An investigation into the incident is continuing.
Lacroix asks anyone with information about the broken glass to contact the Summerland RCMP at 250-494-7416 or Crime Stoppers at 1-800-222-TIPS.
