WASHINGTON (AP) - At least seven people, including three children, were sickened by an apparent carbon dioxide leak while taking part in an annual holiday boat parade in Washington, D.C., authorities say. Authorities responded to a parading 32-foot boat Saturday night after someone aboard fell unconscious and others became ill, fire spokesman Vito Maggiolo told The Washington Post. The person who fell unconscious was a child, according to WUSA-TV.
Of the 16 people on the boat, eight were taken to hospitals in conditions not considered to be life threatening. That number includes an adult who didn’t require treatment but wanted to accompany a child, according to The Post. The other eight passengers were evaluated at the scene and released.
The cause of the leak is unclear, news outlets report. The boat was towed ashore and an investigation is ongoing.
