Adelmi Ruiz, a reporter for Redding, California, ABC affiliate KRCR, was detained at Cal Poly Humboldt while filming police approaching an encampment of pro-Palestinian protesters.

A livestream showed Ruiz filming police in riot gear approaching protesters, who could be heard chanting, when an officer asks her to come over and tells her they need her out of the way.

An officer then tells Ruiz to put her phone away and put her hands behind her back because he is going to put her in flex cuffs -- plastic handcuffs used by police for protesters. Ruiz identifies herself as a reporter multiple times but is still arrested.

"You had an opportunity to leave. You were told multiple times to leave otherwise you were gonna be arrested," the officer says, according to a livestream which continued after Ruiz placed her phone in her pocket.

She responded that she was on assignment covering the protest.

"Find a different job if this causes you to break the law," the officer says.

As she is escorted away, Ruiz can be heard asking for help.

The Humboldt County sheriff has confirmed Ruiz will not face any charges.

The University of Utah has removed an encampment of pro-Palestinian protesters and arrested 17 people after the university said protesters do not have a right to set up encampments on campus property and threatened to disperse them.

About a dozen tents, stashes of water, food and toilet paper were removed from the encampment.

The university had issued warnings to students, staff and faculty members telling them to remove their encampments, or face consequences, including arrests.

The university had threatened criminal trespass and disorderly conduct charges, termination for faculty and staff and discipline for students ranging from probation to suspension against those who refused to leave the encampment.

Pro-Palestinian protesters at Columbia University occupied a hall on campus early Tuesday, hours after school officials ordered the dispersal of a protest encampment.

Videos viewed by ABC News appeared to show protesters creating a barricade with metal chairs outside Hamilton Hall after midnight.

Several were seen in the videos unrolling protest posters from one of the building's balconies.

It was unclear how many demonstrators had occupied the hall, which is on Amsterdam Avenue. The Columbia Spectator, a campus newspaper, reported the people who were inside were working to block the building's exits with tables, chairs and zip-ties.

After police and protesters clashed on the campus of the University of Texas at Austin following a dispersal order, leading to some arrests on Monday, the school issued a statement, saying it "took swift action to preserve a safe, conducive learning environment for our 53,000 students as they prepare for final exams."

"UT Austin requested backup assistance from the Texas Department of Public Safety to protect the safety of the campus community and enforce our Institutional Rules, such as the rule that prohibits encampments on campus. Because of the encampments and other violations of the University’s Institutional Rules related to protests, protestors were told repeatedly to disperse. When they refused to disperse, some arrests were made for trespassing. Others were arrested for disorderly conduct," the university's statement read.

UTA said protests since the start of the Israel-Hamas war have happened "largely without incident."

"The University strongly supports the free speech and assembly rights of our community and we want students and others on campus to know that protests on campus are fully permissible, provided that they do not violate Institutional Rules or threaten the safety of our campus community," the statement concluded.

Over 300 Harvard University professors have signed a letter to the university urging "constructive dialogue" with the peaceful protesters on campus.

"We are concerned that the university has yet to meet with the students to hear their concerns. Instead, the administration has issued escalating threats of punitive disciplinary action, the severity of which the university has not seen in decades," professors wrote.

"We urge the administration to meet and engage in meaningful dialogue with peacefully protesting students," the letter said.

The letter, sent to interim President Alan Garber and interim Provost John F. Manning Tuesday, came after Harvard warned protesters to empty their encampment. The professors are urging Harvard's administration to follow the lead of Brown University and Northwestern University, where encampments ended after school leadership agreed to take steps toward divestment.

"I think so many of us signed this letter because, as faculty, we have a duty of care towards our students. The harshness and scale of the proposed punishment is unprecedented and frankly alarming; these are activities that should be met with dialogue, not punishment," Teju Cole, a Gore Vidal professor of the practice of creative writing at Harvard, said in a statement.

"We are calling on the administration to be fair-minded and set these protests in the context of numerous other protests that have happened here in the past, in response to which the university did the right thing," Cole said.
