A 10-year-old boy was found dead in a Newmarket swimming pool early Saturday morning.
Around 11:30 p.m. Friday, the child’s family told police he had gone to a pool party in their neighbourhood, on Woodfern Way, six hours earlier and hadn’t come home.
Officers searched the area, near Yonge Street and Green Lane, but it was the party host who found the boy around 2:45 a.m.
The coroner was called in, and the boy was pronounced dead.
An autopsy will determine exactly what happened.
York police said they would provide more information at a news conference on Saturday.
