A large majority of the 402 people arrested on the Balboa Peninsula over the Fourth of July weekend appear to have traveled from Arizona, Newport Beach City Manager Seimone Jurjis said on Monday, July 6. He cautioned that arrest data was still being processed but said the connection was clear enough to prompt action, including planned outreach to Arizona's governor.

Jurjis said he spent that morning reviewing reports from the Saturday, July 4 unrest, in which crowds of young people, ages 15 to 25 according to city officials, refused police orders to disperse. He also pointed to social media influencers as a driving force behind the influx.

"You have all the influencers that are influencing the kids to come to Newport Beach and you have people that are here from Newport Beach, from Arizona, that are streaming on TikTok to come to certain parts of the beach," Jurjis told the Orange County Register. "That's where we need to focus our attention."

By the numbers

The city's official press release put the arrest total at 402 between midnight on Thursday, July 3 and 6 a.m. on Saturday, July 5. During the same window in 2025, officers made 60 arrests.

Newport Beach Fire Department personnel responded to 102 emergency incidents on July 4, including 10 fires, and transported 44 patients to local hospitals. Six were trauma patients. One police officer was struck by a mortar firework and evaluated at the scene before being released with non-life-threatening injuries.

More than 350 officers from NBPD and 17 regional law enforcement agencies worked to clear the area. NBPD Deputy Chief Joshua Vincelet described an unruly crowd of close to 3,000 people fighting and causing disruption between 29th Street and 35th Street, saying it took nearly two hours to restore order.

How it unfolded

Councilmember Joe Stapleton, a 20-year Peninsula resident who represents the coastal district, said about 40 arrests occurred Friday night, July 3, with roughly 400 more on Saturday. Approximately 200 people who refused dispersal orders near 28th Street were encircled by police and arrested. Officers worked through the night to book them; once processed, arrestees were loaded onto an Orange County Transportation Authority bus and transported to jail.

At 10:50 p.m. on July 4, NBPD sent alerts through Newport Notified, the city's emergency notification system, announcing all beaches were closed and directing people to avoid the area.

What drew the crowd

Jurjis speculated that Phoenix-area heat and a lack of mountain snow may have pushed Arizona residents toward the coast. He also acknowledged the city's own "Not in Newport" social media campaign, launched by Mayor Lauren Kleiman, may have inadvertently drawn attention, though he said officials are still doing "mental gymnastics" to determine what specifically spurred the influx.

The Newport Beach Police Association said in an Instagram statement that a "large group of agitators invaded Newport Beach, spurred on by an alleged 'TikTok Takeover.'"

What's next

Jurjis said the city will likely reach out to Arizona's governor and, if a link to specific schools is confirmed, to Arizona universities. He indicated a full debrief and policy review of the city's response would come at the next City Council meeting, which he placed the week of July 9.

Municipal Operations crews began removing debris and cleaning Peninsula streets early on Sunday, July 5, and additional officers remained deployed through the weekend. Residents can sign up for Newport Notified alerts at newportbeachca.gov.
