A 3-year-old boy has died in Topeka after an apparent accident on a swing set at a residential day care center.

The Shawnee County sheriff’s office says it received a call shortly after noon Wednesday about an unresponsive child at the home. The boy was taken to a Topeka hospital where he was later pronounced dead.

Authorities say it appears the boy somehow became tangled in the frame of the backyard swing set. Investigators are looking into how the accident happened.

Ten children were at the day care at the time. It’s not clear if any of the children witnessed the incident.
