Following Donald Trump's rally in Costa Mesa, California, Thursday night, hundreds of protesters lined the streets, blocking cars leaving the OC Fair & Event Center, while other jumped on police cars.
The Orange County Sheriff's Department said protesters were detained and arrested, but did not provide a figure. There were nearly 200 officers outside the Trump rally, according to the Sheriff's Department
The protesters were met with police in riot gear and others mounted on horseback.
Protesters jumped on police cars and other vehicles, and tossed water bottles and other objects at the police. At least one police car was damaged by the protesters. Protesters were also filmed trying to flip over a police car.
Rebeca Olguin, a Bernie Sanders supporter who was at the scene and posted a video of the mayhem on Instagram, told ABC News she came to protest Trump and his campaign.
"There were some who were peacefully protesting while others were being more open about sharing their opinions," she wrote in an e-mail to ABC News. Olguin also told ABC News Trump supporters were making racist comments and talking about building a wall, and the Trump protesters would subsequently respond.
Before the event started, the venue closed once it had reached capacity and individuals were trying to jump the fence to get in. They were escorted outside the gate.
