Santa Clara Police made 11 arrests and ejected 45 individuals following multiple violent fan brawls during Sunday's 49ers vs. Raiders game at Levi's Stadium. The confrontations marred the matchup, which saw the San Francisco 49ers defeat the Las Vegas Raiders 38-17.

Lt. Eric Lagergren of the Santa Clara Police Department stated that public safety and security staff responded to all reported incidents of fan-on-fan violence. The department is currently investigating several of the altercations that were captured on video and shared on social media.

"Incidents of violence at large-scale events in Santa Clara will not be tolerated," Lagergren said in a statement. "The Department strictly enforces the law and holds individuals accountable for criminal conduct. We will seek to arrest the individuals responsible for the fan-on-fan violence at the event."

Some of the most severe fights occurred outside the stadium, with multiple people reportedly losing consciousness. Videos circulating online showed combatants continuing to strike individuals who were already on the ground.

49ers defensive end Keion White acknowledged that players on the field noticed the disturbances. "We were seeing people fight in the stands," White told reporters after the game. Offensive lineman Trent Williams also commented on the heightened atmosphere, noting, "The fan engagement with this game is nuts. It’s through the roof."

Police are encouraging anyone who witnessed violence at the stadium to contact the Santa Clara Police Department at 408-615-4700 or use the department's Anonymous Tip Line at 408-615-4847.
