Four men have been arrested on suspicion of hate crime and battery offenses after Berkeley police said a confrontation outside a student co-op party turned violent. Police allege that one person was targeted with a metal barricade and then punched in the head. The incident occurred last Friday night in the 2300 block of Prospect Street, near cooperative student housing and the UC Berkeley campus.
Police said the confrontation began around 11 p.m. after a group was denied entry to the party, according to The Berkeley Scanner. Investigators allege that one member of the group took a metal barricade and attempted to strike someone, while others punched the targeted person in the head. People who intervened were also attacked, the outlet reported, citing Berkeley police.
Authorities say the party was connected to Berkeley Student Cooperative housing that hosts LGBTQ+ community events. The 2300 block of Prospect Street sits amid a cluster of BSC-run residences, including the Person of Color Theme House on Warring Street, the African American Theme House at 2347 Prospect, and Sherman Hall at 2250 Prospect, according to the Berkeley Student Cooperative. The cooperative system also includes Oscar Wilde House on nearby Warring Street, established in 1999 as the nation's first student co-op dedicated to LGBTQIA+ students, per the cooperative's own history.
Injuries and Hospital Visits
Berkeley police say victims did not require ambulance transport at the scene, though at least one victim went to the hospital independently afterward, the station's report noted. Police documented the incident as a hate crime following the confrontation.
How hate-crime reports are tracked
The Berkeley Police Department's annual report includes information about the department's Transparency Hub. For campus-related concerns, UC Berkeley's Office for the Prevention of Harassment & Discrimination advises people to report hate crimes to local law enforcement and directs campus community members to the University of California Police Department. The Berkeley Student Cooperative describes its Person of Color Theme House as affordable housing for low-income, first-generation, immigrant and marginalized students, among others, according to UC Berkeley's harassment and discrimination office and the Berkeley Student Cooperative.
The four arrested men are Jose Gutierrez Ruvalca, 20, of Martinez; Jadrien Lopez, 20, of Martinez; Rey Dona Hermosillo, 20, of Martinez; and Nydin Trinidad, 19, of Concord. Booking information cited in the report lists each man on suspicion of felony battery with serious bodily injury, battery, conspiracy and a hate crime. Hermosillo also faces suspicion of assault with a deadly weapon, while Lopez and Trinidad each face suspicion of robbery.
Legal Process Moves to Oakland Courthouse
As of Monday, booking records cited in the report showed all four men in custody at Berkeley jail. Their arraignment was scheduled for Wednesday at 9 a.m. at the Wiley Manuel Courthouse in Oakland. At that hearing, defendants are formally informed of the allegations, enter preliminary pleas and may have bail conditions evaluated, according to Gorelick Law Offices.
Under California Penal Code Section 422.55, a hate crime is defined as any offense committed in whole or in part due to a victim's actual or perceived protected characteristic, meaning prosecutors do not need to prove bias was the sole motive. California law also addresses bias-motivated crimes in Section 422.75, according to FindLaw.
Anti-LGBTQ Bias a Persistent Pattern Locally
Anti-LGBTQ hate crimes are the second-largest category of hate crime reported in Berkeley, making up about 20% of the city's hate crime reports over the past decade, per the Berkeley Scanner's reporting. The city has recorded seven other anti-LGBTQ reports so far in 2026, and its overall hate crime tally of 38 reports this year appears to be keeping pace with last year's peak of 54.
The pattern echoes statewide data. The U.S. Department of Justice found that sexual orientation bias made up 21.9% of all reported hate crime incidents in California in 2023, making it the second-largest bias motivation category statewide, according to the United States Department of Justice. Statewide, total reported hate crime events dipped 3.4% from 2,023 in 2024 to 1,955 in 2025, per the California Department of Justice's 2025 Hate Crime Report released in July.
Part of a Wider Run of Bias Cases Near Campus
The Prospect Street case adds to a string of bias-motivated prosecutions tied to the UC Berkeley area. In August, a Berkeley man was convicted of felony arson for burning a mezuzah at Berkeley Hillel near campus in 2024. Alameda County law enforcement agencies recorded 160 reported hate crime offenses in 2023, according to state Department of Justice data.
In December 2025, Alameda County prosecutors charged a 35-year-old UC Berkeley student with felony vandalism following a series of antisemitic graffiti incidents at the university's University Village residential complex in Albany. University authorities may issue timely warnings about violent or bias-motivated crimes occurring on or near campus.
