CHICAGO — A man was killed and more than a dozen injured on Sunday when a tent where people had sought shelter during a brief storm blew off its moorings and collapsed on some of the crowd at a festival in a Chicago suburb.

Mike Rivas, deputy police chief in the suburb of Wood Dale, said three people were seriously injured. Fifteen people were transported to the hospital and others slightly injured were treated at the scene and released, Wood Dale police said in a statement posted on Facebook.

The fatality was identified as Wood Dale resident Steven Nincic, 35.

The incident happened at midafternoon when a sudden storm brought high winds, hail and rain to the annual Prairie Fest, Rivas said.

“People sought shelter under the tent and then it hit,” he said of the storm.

The tent was ripped from its moorings and fell on some people, said Craig Celia, a spokesman for Wood Dale, which is about 25 miles northwest of Chicago. The remainder of the festival’s final day was canceled, he said.
