College protests updates: Police crackdown leads to hundreds of arrests

The Columbia University Senate is set to establish a task force to investigate the school's administration after their actions, or lack thereof, have divided the university community, the University Senate announced Friday.

The senate alleges the university jeopardized academic freedom by threatening "faculty job security," breached privacy and due process by disregarding "privacy and due process rights of individual students and faculty members."

The Senate also accuses the university of creating a violation of shared governance principles.

"The decision by the University administration to call for police intervention on campus, after the Senate Executive Committee told the administration that the Executive Committee did 'not approve the presence of NYPD on our campus at this time,' has raised serious concerns about the administration’s respect for shared governance and transparency in the University’s decision-making process," the statement read.

Actions by the university and its administration showed "little respect for clearly established protocols," the Senate said.

California State Polytechnic University's Humboldt campus will be closed through the end of the semester amid ongoing pro-Palestinian protests, the university said Friday.

The campus will be closed through May 10, with remote academic instruction instead, due to the occupation of its Siemens Hall and Nelson Hall East buildings, the university said.

"Since Monday night, protestors have attempted several times to break into multiple locked buildings with the intention of either locking themselves in, vandalizing, or stealing equipment," the university said in a message to the school community. "Vandalism and theft have continued across campus."

The university said protesters -- including students and non-students -- have until 4 p.m. PT Friday to leave the buildings peacefully "with a guarantee of no immediate arrest."

"This does not, however, eliminate University conduct-related sanctions or legal implications," the university added.

Videos online show sprinklers were turned on where Arizona State University students set up a pro-Palestinian encampment, demanding that the university divest. Students set up their encampment on Friday.

Videos show protesters putting bags and items on top of the sprinklers to stop them from spraying.

More videos show tense interactions between students and ASU police responding to the scene. At least three individuals are seen being arrested, Phoenix ABC affiliate KNXV reported.

The lead student negotiator with a Columbia University student group organizing the encampment says there is no longer a "deadline" for them to leave, but more of a "timeline."

The group -- Columbia University Apartheid Divest group -- says negotiations with the university remain ongoing and another decision will be made at 5 p.m.

"We have until 5 p.m. to come up with a plan," the Columbia student negotiator said.
