The LAPD and California Highway Patrol are facing backlash over not intervening in the UCLA protests sooner, as violence broke out overnight, however, law enforcement sources told ABC News the hesitancy came from jurisdiction over the campus.

The LAPD and CHP don’t have jurisdiction over UCLA and cannot unilaterally race in because UCLA has its own full-fledged police department and dispatch center, sources said.

The delay, as described by sources, was due to UCLA and its police department not authorizing a response.

UCLA’s limited police force was overwhelmed and tried to deal with the protest internally, according to sources, until the call to the LAPD and CHP was eventually made.

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

In a press briefing Wednesday, Ben Chang, a Columbia University spokesperson, addressed the over 200 arrests made Tuesday evening, stemming from the ongoing protests.

The NYPD confirmed that the arrests from last night numbered 202, with 109 being from Columbia University.

"These were not peaceful protesters," Chang said. "I surveyed the damage myself, and as the president has indicated, severe damage was inflicted on that building."

In response to the disruptions, Chang said the university leadership, backed by the trustees, decided to call in the NYPD to help restore order.

Academic activities at Columbia will continue remotely for the remainder of the semester, according to Chang, who noted, the university is making adjustments to ensure that final exams and assessments proceed smoothly.

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."

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.
