GRAND FORKS, N.D. – A gay 18-year-old who crashed a University of North Dakota party then claimed he was a victim of a hate crime when he was kicked out will not face criminal charges for lying to police.

The University Police Department’s investigation into an August party at UND’s Lambda Chi Alpha fraternity house where Haakon Gisvold alleges his was kicked out, stripped and beaten for being gay concluded Gisvold made up the allegations, the Grand Forks Herald reports.

Gisvold, who is not a student at the school, told police he was at the party when his was attacked by multiple men, who stripped his clothes and assaulted him while hurling homophobic slurs. Grand Forks and UND police identified 150 witnesses to the incident and questioned many who were sober. They told officers it was Gisvold who instigated a fight after he tried to smoke inside the fraternity, which is prohibited. Even Gisvold’s friends told police his story was baloney.

“He was not held down by four people, he wasn’t robbed, his property wasn’t taken, he wasn’t beaten with a belt, and he was (not) assaulted,” according to the police report.

Witnesses said Gisvold came to the party in an American flag tank top and red spandex shorts, and was making people feel uncomfortable. When Gisvold attempted to smoke a cigarette in the house, he was escorted outside, where he engaged in a debate about his removal with another person – whose name was redacted from a police report obtained by the Herald.

The debate turned into a verbal altercation, which turned to shoving, and Gisvold eventually grabbed the person by the hair and punched him in the head multiple times, witnesses told police.

Witnesses also said Gisvold took off his own clothes, “either in anger or out of frustration,” according to the police report.

UND President Robert Kelley sent a campus email out about the “disturbing” allegations shortly after the incident and disavowed the violent attack. The email sparked criticism about drawing premature conclusions amid the ongoing criminal investigation, WDAZ reports.

UND issued another statement after the investigation concluded that made no apologies.

“We will review the information and determine any next steps for the University in compliance with federal regulations as they refer to Title IX and the Code of Student Life,” the statement read, according to the news site. “We continue to strive for a safe and welcoming environment for all within our campus community.”

Fraternity members said the weeks following the accusations have been a whirlwind.

“Throughout this whole time it’s been a real stressful situation, I mean everybody was getting phone calls from their grandparents, their aunts, uncles, their parents asking what did you guys do?” Lambda Chi Alpha member Eric Hanson said.

“When I walked out of the house, basically all I saw was an altercation, someone being belligerent, not wanting to leave even though they were causing problems in the house,” he said.

“We were just really relieved to have the truth come out,” fraternity president Joe Price told the Herald.

Grand Forks police sent the case to the county prosecutor to pursue charges for filing a false police report, but prosecutors refused to hold the student accountable, according to a statement by the Grand Forks County State’s Attorney’s Office.

County prosecutor David Jones provided a statement to WDAZ on why he won’t pursue the case.

“While probable cause may exist to conclude that such an offense took place, at this time there is not a substantial likelihood of conviction, as such pursuing a criminal charge is not deemed to be in the interest of justice,” he wrote.

The statement by the Grand Forks County State’s Attorney stated “the initial report to law enforcement alleging the victimization of Gisvold was made by his father, who was understandably taking a protective position concerning his son,” according to Valley News Live.

“I should be emphasized that there was no finding of derogatory or discriminatory practices by any individuals associated with Lambda Chi Alpha fraternity,” it continued. “Said members were fully cooperative in the investigation of this matter, and members of that fraternity initiated contact with law enforcement on the morning of August 30th as a result of these activities which had taken place outside their house.”
