As pro-Palestinian protests have erupted on college campuses nationwide, protesters — including students and faculty — continue to be arrested since the first demonstrators were detained at Columbia University two weeks ago. More than 250 protesters were arrested on May 2, after April 30 saw the largest number of arrests in a day since protests began with nearly 400 arrests, according to a CNN review of university and law enforcement statements.

More than 2,100 people have been arrested on college and university campuses since April 18 as schools prepare for spring commencement ceremonies, according to CNN’s review. The University of Southern California, where nearly 100 protesters were arrested April 24, canceled its primary commencement event. Protesters have been arrested on more than 40 campuses across at least 25 states. Many other schools have experienced protests without arrests.

Protest demands vary from campus to campus, but a major focus is that universities divest from companies with financial ties to Israel amid its war with Hamas. There have also been counter-protests, resulting in clashes at UCLA.
