A University of Colorado student has been arrested after police say he threw a glass and broke another man's nose at a bar in downtown Boulder last month.
Spencer David Klavsons, 21, was arrested on suspicion of second-degree assault and is being held at the Boulder County Jail on $5,000 bond as he awaits a formal filing of charges on Tuesday.
According to an arrest affidavit, two men — Eduardo Samayoa and Grant Jensen — were in the VIP section of the Pop-Up Bar, 1109 Walnut St., in the early morning hours of Feb. 16 when Samayoa started talking to a woman he knew outside the VIP area.
Witnesses said Klavsons, who was an ex-boyfriend of the woman, saw the conversation and began punching and hitting Samayoa. When Jensen came to help break up the fight, Klavsons reportedly threw a glass tumbler at him, breaking Jensen's nose and giving him a slight concussion.
Klavsons was kicked out of the bar by employees, according to the affidavit.
While Samayoa elected not to pursue a case — which police say likely would have resulted in third-degree assault charges — Jensen called police the next day to report the incident.
Police talked to another witness who knew both Samayoa and Klavsons, and she said she also saw Klavsons "very, very violently" throw the glass. That witness also thought she might have seen Jensen throw a punch at Klavsons, but no other witnesses saw a punch and police believe the two were not close enough for Jensen to have reached him due to the railing separating the VIP section from the area where Klavsons was.
Witnesses also said Klavsons was highly intoxicated and also may have used cocaine at some point during the night, according to the affidavit.
Klavsons, through his attorney, declined to talk to police. He turned himself in to police on Thursday.
He is listed as a economics major on CU's online database. Court records show he does not have any prior criminal history in Colorado.
