Police said a band called the Dead Presidents was playing at Evergreen State College when a fight broke out within the crowd at about 1:30 a.m.

As a campus police officer responded and tried to make an arrest in the brawl, she was surrounded by a crowd of concert-goers.

Police said as she struggled to remove the man from the crowd, the band onstage started playing a song called “F___ the Police,” and the audience became increasingly agitated and combative.

Washington State Patrol Trooper Brandy Kessler said the crowd surrounded the officer’s car, demanding for the arrested man to be released.

The officer called for backup. Thurston County deputies responded and removed the campus officer from her car and released the arrested man.

When a deputy’s car failed to start, the crowd overturned it, breaking out windows and ripping the car apart. Officers were pelted with rocks during the melee.

Officials said a deputy's laptop computer and a radar gun were stolen. No weapons were lost.

Troopers and a Thurston County SWAT team dispersed the crowd. No further arrests were made.

One officer was hurt by pepper spray in his eyes.
