Boulder police arrested a University of Colorado football player after they say he lit the contents of a metal bucket on fire at a Pearl Street bar and then refused to leave early Sunday morning.

William Garrett Pericak, 21, a starting defensive lineman for CU, was arrested on suspicion of physical harassment and trespassing, according to a police report.

According to the report, at around 1 a.m. Sunday, a bartender at the Pearl Street Pub and Cellar at 1108 Pearl St. said Pericak lit the contents of a metal bucket on fire. Bartenders said the bucket contained trash and miscellaneous papers and were able to put it out with no damage to the bar.

When the bartender asked Pericak to leave, he refused and then started swearing and walked aggressively towards the bartender, police said. The bartender told police Pericak then gave the bartender what he described as a "chest-bump."

The bartender told police Pericak fled the bar when police were called. The bartender followed Pericak and police contacted him near Broadway and Walnut Street.

Pericak initially told police he was never on Pearl Street. In the report, police noted Pericak appeared to be "heavily intoxicated." Pericak later told police, "Listen, I had some beers and caused some trouble, but I haven't done anything illegal... I left the bar."

Pericak, who graduated from Boulder High, played in 13 games for the Buffs and was fourth on the team in tackles with 64 in 2011, his junior season.

Dave Plati, a spokesman for CU athletics, said head coach Jon Embree is aware of the arrest but is waiting for the case to be resolved before making a decision on any disciplinary action.

Pericak is free on bond. He did not return calls for comment Tuesday afternoon.

In January of 2011, Pericak and two other CU football players were investigated for vandalism after security tapes in a Denver parking garage caught one of the players kicking a car. The players paid for damages and no charges were filed.
