Preston Jeffery Olson, 36, of Thief River Falls, was cited for domestic assault. He was arrested, according to the citation.
According to the citation, Olson and his boyfriend argued at the residence. The dispute involved an allegation of infidelity, the citation said.

The citation noted that both men were highly intoxicated on alcohol. No additional injury details were listed in the brief report.
What happens next
The report did not list a court date or bail details. Those details often appear after booking and court filings.
Domestic assault reports are typically reviewed by prosecutors. A citation can also be followed by a formal criminal complaint.
That review can take time. Charges can also change after that review.
Olson is presumed innocent in court. The allegations in a citation are not proof.
TRF News is not naming the reported victim. The victim was identified as Olson’s boyfriend in the report.
