A pro-Palestinian tent encampment on the University of Southern California campus was cleared out and dismantled Sunday morning without any arrests being made, university officials said.

Joel Curran, a spokesperson for USC, said in a statement that the encampment, established by protesters 12 days ago, was "peacefully" taken down.

“Earlier today, the University of Southern California Department of Public Safety (DPS) successfully removed the illegal encampment rebuilt on the university’s campus. It was necessary to request the Los Angeles Police Department to respond to provide security as this was carried out peacefully," Curran said. "No arrests have been reported. We want to thank LAPD for assisting DPS in clearing the encampment and restoring normalcy for students and community as quickly and safely as possible. We will share more information with our community later today.”

The University of Southern California said the encampment at University Park Campus has been cleared and the campus remains closed.

A pro-Palestinian encampment on the campus of the University of Southern California was being cleared Sunday morning as campus police warned protesters to leave or be arrested.

The announcement came as the USC Department of Public Safety closed the campus "as a result of significant activity at the center of campus."

"If you are in the center of campus, please leave. People who don’t leave will be arrested. We will issue another alert when it is clear to return," the DPS said on X.

The campus police said officers from the Los Angeles Police Department are assisting in "clearing the center" of the University Park Campus.

Sunday's action came after USC President Carol Folt sent an email to the school's community, saying "steps would be taken to ensure a quiet and safe environment for students to complete their finals."

“[L]et me be absolutely clear: free speech and assembly do not include the right to obstruct equal access to campus, damage property, or foment harassment, violence, and threats,” Folt said. “Nor is anyone entitled to obstruct the normal functions of our university, including commencement."

Authorities arrested 25 protesters at the University of Virginia for trespassing on Saturday, according to the university's communications office.

The school said it was still awaiting confirmation on how many of those arrested were affiliated with UVA.

New York City Mayor Eric Adams urged protesters at Columbia University to "walk away" after dozens of demonstrators stormed the campus' Hamilton Hall in what he called a "violent spectacle that serves no purpose."

Adams said the peaceful demonstrations were being co-opted by "professional outside agitators" seeking to "create discord and divisiveness."

"That is why I'm urging every student, every protester to walk away from this situation now. Continue your advocacy through other means," Adams said at a press briefing Tuesday evening. "We will always protect the right to protest, but we must balance that right with the right to keep students in school and our city safe."

"We cannot wait till this situation becomes even more serious. This must end now," he added.

Chief Edward Caban reiterated that protesters who are not Columbia students are working to escalate the situation and said the New York City Police Department is ready to assist the university as needed.

"We have seen the tactics changing in a way that's endangering public safety," he said.

The NYPD showed footage of what Deputy Commissioner for Intel Rebecca Weiner said showed outside actors making barriers inside Hamilton Hall and "escalating" tactics such as scaling buildings and breaking windows. Cameras in the building have also been destroyed, Weiner said.

Individuals who occupied Hamilton Hall could face charges including burglary in the third degree, trespass and criminal mischief, police said.

A Columbia University spokesperson said Tuesday evening that dozens of protesters were in Hamilton Hall.
