Eugene police arrested four people and handed out several citations following a Saturday night riot involving some 400 people near the University of Oregon campus.
Officers were working a regular "party patrol" west of campus when they encountered the large crowd at about 11:20 p.m., police said. All available officers were called to the gathering at 13th and Ferry streets, along with additional personnel from the Lane County Sheriff's Office, the Springfield Police Department and Oregon State Police.
The crowd ignored commands to disperse, chanting obscenities while throwing bottles and other objects at officers, according to police. The unruly gathering also broke car windows and tore down street signs, police said.
Officers used tear gas to scatter the crowd, getting the situation under control shortly after midnight, police said. Further patrols in the area continued throughout the night.
Many university students moved back to Eugene earlier this week. Fall term classes begin Monday.
Arrested as a result of the fracas were Odin VanNorman Erickson, 24, Lauren M. Nunez, 21, Brett Joseph Mattos, 21, and Derik Ryan Brown, 19. Erickson, identified by police as a transient, was charged with riot, two counts of third-degree criminal mischief, interfering with police and possession of marijuana.
Five other people, ages ranging from 19 to 22, were cited with minor charges but not arrested.
