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."

UCLA officials issued an evacuation order for all protesters in the area of Royce Quad, saying the encampment was "unlawful."

Smoke billowed around law enforcement officials as they began breaking through the barricades on the campus encampment. It was not immediately clear whether the smoke had been dispersed by the police or the protesters.

The encampment in Dickson Plaza, along with all unauthorized tents and structures, had been declared "unlawful," campus public safety officials said in an alert.

"The University requires that everyone must leave the encampment and adjacent areas, as well as all unauthorized structures and tents immediately, until further notice," the alert said.
