Of the approximately 280 arrests at Columbia University and City College, 170 are summonses, while the remaining people will receive desk appearance tickets or will work through the court system, according to Manhattan District Attorney Alvin Bragg.

Each case would be evaluated individually, including a review of body camera footage and other evidence, Bragg said. But, he did not reveal how many of those arrested were affiliated with the colleges and how many were outside agitators.

Columbia University announced final exams will be held remotely amid a tense campus climate, according to a letter sent out by the university's provost.

"In order to address the concerns of our members in an evolving campus environment, all academic activities for schools on the Morningside Heights campus will be fully remote for the remainder of the semester (with carve-outs noted below). Any remaining class meetings, review sessions, or office hours should be held fully remotely, and all final exams and other final assessments should be fully remote," Columbia said in a statement.

All final exams scheduled for Friday will be automatically rescheduled for May 10.

A total of 34 people were arrested while emptying a pro-Palestinian encampment at University of Wisconsin-Madison Wednesday, the university said.

The majority of those arrested have been released with no citation issued, but four people have been booked, according to the university. The charges they are facing include attempted disarming a police officer, resisting arrest, attempted escape and battery to a police officer.

Four police officers were injured at the University of Wisconsin-Madison where police were dispersing an encampment of protesters on the Library Mall.

Three of the four officers sustained injuries "directly related to the physical resistance," according to the university. A state trooper sustained injuries when a protester allegedly "struck their head with a skateboard."

The University of Minnesota has reached an agreement to end the student-led encampment on campus.

The university will reopen previously closed buildings and the student coalition has pledged not to organize disruptions during final exams and the commencement ceremony.

Representatives of the student coalition will be given the opportunity to address the Board of Regents at its May 10 meeting over its call for a divestment, students will receive amnesty for their encampment, and the university will also explore an affiliation with Palestinian universities, hosting scholars at risk.

"Our meetings have been grounded in listening, learning, and respect, and I believe they were a very positive first step in reaching mutual understanding. Though the original meeting was scheduled for 30 minutes yesterday, we engaged in constructive conversation for more than 90 minutes. We then met two more times to discuss the proposed agreements," University of Minnesota interim President Jeff Ettinger said in a statement.

"We regret that these meetings did not happen sooner, and have committed to regular meetings moving forward to continue to discuss this coalition’s concerns," Ettinger said.

Ettinger also highlighted that the university supports freedom of expression as a fundamental part of its mission.

"While we do not condone tactics that are outside of our policies, we appreciate student leaders’ willingness to engage in dialogue. I value the challenging and healthy conversations we’ve had," Ettinger said.
