NYPD Deputy Commissioner Kaz Daughtry said Fordham University requested NYPD assistance in clearing an "unlawful encampment of individuals inside one of their buildings," in a statement posted to X on Wednesday.

Daughtry said individuals who refused to disperse from the encampment were placed inside a building at Fordham under arrest.

Los Angeles Mayor Karen Bass addressed the protests that turned violent overnight at UCLA in a statement Wednesday, saying she met with Los Angeles police, sheriffs and other agencies.

"This morning, I met in person with LAPD, LASD, CHP, CalOES, UCPD and other regional agencies at the UCLA incident command post about the absolutely detestable violence on campus last night," Bass said.

Bass warned that any demonstrator involved in "launching fireworks at other people, spraying chemicals and physically assaulting others will be found, arrested, and prosecuted, as well as anyone involved in any form of violence or lawlessness."

The mayor noted that she's spoken to California Governor Gavin Newsom and thanked him for "his continued support."

The day after protests turned violent at UCLA, faculty members held a conference addressing the protests and the university’s response.

"Last night I went to bed at around 4:00 a.m. with student’s blood on my hands and I'm not speaking figuratively," UCLA Assistant Professor Nicholas Shapiro said. "I mean, a student collapsed into my hands with blunt force trauma and mace in their eyes, and I had to treat them."

The protests led to 15 injuries, including one hospitalization, according to officials.

"This is a failure of our institution and we need to put a stop to it today," Shapiro said.

UCLA Associate Professor Bharat Venkat also addressed the violent scene on campus, saying, "It felt like walking through a war zone."

"They're screaming, they're crying," Venkat said of the student demonstrators. "They're having a difficult time breathing. This shouldn't be happening anywhere and this shouldn't be happening here at UCLA."

University of California President Michael V. Drake addressed the ongoing protests at UCLA that "turned violent" overnight, announcing in a statement on Wednesday an "independent external review" has been ordered.

The university summoned mutual aid from LAPD officers to "restore control" to the protest, according to Drake, who noted, there were 15 injuries, including one hospitalization, that stemmed from the protest.

"My office has requested a detailed accounting from the campus about what transpired in the early morning hours today," Drake said.

"But some confusion remains, therefore we are also ordering an independent external review of both UCLA’s planning and actions, and the effectiveness of the mutual aid response," Drake said.

UCLA's own chancellor, Gene D. Block, also promised an investigation.

"We are still gathering information about the attack on the encampment last night, and I can assure you that we will conduct a thorough investigation that may lead to arrests, expulsions and dismissals," Block told the campus community in a note Wednesday afternoon.

Block, in his note, said it was "a group of instigators" who came to Royce Quad to "forcefully attack the encampment that has been established there to advocate for Palestinian rights."

He called the overnight violence "utterly unacceptable."

"However one feels about the encampment, this attack on our students, faculty and community members was utterly unacceptable. It has shaken our campus to its core and — adding to other abhorrent incidents that we have witnessed and that have circulated on social media over the past several days — further damaged our community’s sense of security," his letter read.

In a letter authorizing the NYPD to enter the Columbia University campus and break up the protest, the school detailed the backstory on its recent talks with those in the encampments and the takeover Tuesday night of Hamilton Hall.

According to the letter, from Columbia President Minouche Shafik, an individual "hid in the building" at Hamilton Hall until it was closed and let others in. The group's purpose was "occupying the building," the letter read.

Two security guards were inside the building at the time, and the university said in the letter to the NYPD they were able to "secure their release."

"We believe that while the group who broke into the building includes students, it is led by individuals who are not affiliated with the University," the letter read. "The individuals who have occupied Hamilton Hall have vandalized University property and are trespassing."
Addressing the encampment on the school's Morningside campus, the university told police discussions had been carried out with group representatives, but on Sunday, they "reached an impasse."

At that time, the university says it told the group they did not have permission to "occupy spaces on campus" and were "in violation" of school rules and policies.
On Monday morning, the protesters were told they would be suspended if they didn't disperse by Monday at 2 p.m. ET.

The university said in its Tuesday night NYPD letter that those in the encampment were "suspended" and "not authorized to be on University property and are trespassing."

The university said it believed the actions of those in the protest were escalating. "These activities have become a magnet for protesters outside our gates which creates significant risk to our campus and disrupts the ability of the University to continue normal operations," the letter read.

Columbia's president concluded the letter by asking the NYPD to "help to clear all individuals from Hamilton Hall and all campus encampments."

She further asked police to have a campus presence through May 17 -- graduation is May 15 -- "to maintain order and ensure encampments are not reestablished."

Police moved onto the Columbia University campus a little before 9 p.m. ET and began making arrests.

The NYPD also used a vehicle with an extendable roof ramp to help officers breach Hamilton Hall from an upper floor. From there, the police cleared the building.

The campus encampment and hall were cleared before 11:30 p.m.
