A Utah student has been arrested after threatening to detonate a nuclear reactor on campus if the Utah football team did not beat San Diego State in its Week 3 matchup at Rice-Eccles Stadium.

According to Pat Reavy of KSL.com, the 21-year-old woman was booked into the Salt Lake County Jail for investigation of making a threat of terrorism:

The woman “posted threats of violence” on the Yik Yak app before the game, stating that “if the football team did not win the game, (she) was going to detonate the nuclear reactor that is located in the University of Utah causing a mass destruction,” according to a police booking affidavit.

Police note in their affidavit that the student does have knowledge of the nuclear reactor and “is aware of where the reactor is located and attends class in the same building where the reactor is housed.”

On Thursday, the University released a statement regarding the arrest, saying that even though the student claimed her comments were a joke, the school has “a zero-tolerance policy for these kinds of threats.”

University of Utah police also noted that the school’s nuclear reactor “is secured and alarmed and police have unique protocols for managing any breach of the facility,” per Reavy.

Rest assured, Utah beat San Diego State handily, a 35-7 result that was never in doubt.
