A couple of University of Iowa fans took a break from Saturday’s game at the Metrodome against the University of Minnesota to have some illicit sex in a Dome restroom, police said.

The duo — a 38-year-old woman and a 26-year-old man from Carroll and Linden, Iowa, respectively — turned a handicapped toilet stall into their love nest about 8:30 p.m., late in the Hawkeyes’ 55-0 trouncing of the Gophers.

A crowd of intoxicated fans gathered in the restroom to laugh and cheer the off-the-field action, until an Avalon Security guard tipped off University of Minnesota police to the ruckus.

Officers had to interrupt the intimate moment to cite the couple for indecent conduct, a misdemeanor.

University of Minnesota Police Chief Greg Hestness said similar citations at the Metrodome or on campus usually involve public urination.

He said it was the first time in his six years at the U that his force has interrupted a sex act during a Gophers game.

Hestness assumed the woman was embarrassed about being caught: She initially gave a false name to officers and had to be identified by her husband before she was released.

The man was attending the game with his girlfriend, according to police.

“It’s a long ride back to Iowa,” Hestness said.
