Nearly 50 people were arrested after hundreds of anti-Israel protesters swarmed the campus of UC Irvine in California and set up barricades, the university confirmed Thursday. 

The university said that the 47 individuals arrested were charged with trespassing or failing to disperse after a direct police order. 

The booking process began on campus and those arrested were taken to the Orange County Jail, where booking and processing were completed. They were then released, university spokesperson Tom Vasich said.

UC Irvine confirmed later Thursday that of the 47 individuals arrested, 26 were students, 19 were non-affiliates, and two were employees.

The university moved to remote operations on Thursday.

A UC spokesperson told Fox News Digital on Wednesday that the campus erupted into chaos after several hundred protesters entered the Physical Sciences Lecture Hall on the California campus and began to barricade the building.

Chancellor Howard Gillman issued a statement late Wednesday saying he was planning to allow the peaceful encampment to remain on campus even though it violated university policies, but the school called in police after a small group barricaded themselves inside a campus lecture hall, supported by a large group of community members rallying outside.

He said the group transformed what had been a manageable situation into one that required police response and demanded to oversee many elements of university operations.

"Most importantly, their assault on the academic freedom rights of our faculty and the free speech rights of faculty and students was appalling," Gillman said in the statement.
