ROYAL OAK, Mich. (AP) — Fifty-five people were taken to a hospital Saturday after high levels of carbon monoxide were detected at a high school pool during swimming lessons, police said.
The children and adults were transported to Beaumont Hospital after many of those inside Dondero High School were sickened, Royal Oak police Sgt. Barry Gale said. Police were called after 10 a.m. and laid those sickened on a sidewalk outside the school, he said.
Gale said testing by the fire department determined high levels of carbon monoxide inside the pool area. He said it was believed to have been caused by a malfunctioning furnace.
