The family of a 12-year-old Manitoba boy who was injured on the weekend after a piece of playground equipment collapsed say they want answers about what happened.

Six children, including 12-year-old Joshua Magri, were on the playground structure at the East St. Paul municipal sportsplex on Sunday afternoon when part of the structure detached and collapsed on them.

Joshua, who suffered a concussion as a result of the incident, said he and the other kids had been on the structure for just a few seconds when it came apart.

"I tried to get up," he told CBC News on Monday.

"My mom said I blacked out for a bit, and they laid me down and people were trying to, like, help me stay awake."

Another boy hurt his arm in the incident, Joshua said.

His parents, Tiffany and John Magri, say they are worried there may be other unsafe playground structures in the area.

"You want to be able to trust that you send your kids to play somewhere and they're going to be safe on that equipment," John Magri said.

"I mean kids will get injured -- they're going to fall, they're going to scrape their knee — but not that the equimpent is going to break."

Officials with the Rural Municipality of East St. Paul say the play structure is three years old and was visually inspected as recently as two weeks ago by municipal staff.

The company that installed the structure, Blue Imp, told CBC News that it is investigating the incident and contacting other customers to let them know what happened.

Don Scott, a spokesman for the company, said staff haven't had a chance to inspect the equipment in East St. Paul. It's not clear yet if it will need to be recalled.
