A Saturday night carbon monoxide leak at a Glen Ellyn ice rink sent more than a dozen hockey players and fans to local hospitals.

Glen Ellyn Fire Department Public Information Officer Craig Eldridge said firefighters got a call at 5:33 p.m. of a possible gas leak.

Arriving at the Highland Avenue rink five minutes later, firefighters found a high presence of carbon monoxide and evacuated the rink.

The rink, which was hosting the Bauer International Invite hockey tournament at the time, "was packed with people," Eldridge said.

The tournament attracts top youth travel teams from across the United States and Canada.

The tournament Web site Saturday asked managers and coaches originally slated to play at Center Ice to keep checking for updates on where they would be playing.

"When arenas are found, we will ask you to call Tourney (headquarters) for info," the message read.

Dozens of individuals were complaining of headaches, dizziness and vomiting.

Firefighters upgraded the incident to a second-alarm, and surrounding fire departments - including Wheaton, Lombard, Downers Grove, Villa Park, Winfield, Carol Stream, Glenside and Bloomingdale - assisted.

Thirteen people were taken to Central DuPage and Glen Oaks hospitals, and 29 others were treated on the scene, Eldridge said.

The cause of the leak is still under investigation.
