Yale authorities on Tuesday morning cleared a protesters’ encampment after students heeded final warnings to leave, university officials said. No arrests were reported.

Demonstrators said on social media that they were moving their gathering to a sidewalk area. The encampment was set up Sunday, six days after police arrested nearly 50 people, including 44 students, and took down dozens of tents.

At California State Polytechnic University, Humboldt, where protesters have occupied two buildings, dozens of police officers in helmets and carrying batons marched onto campus early Tuesday and cleared both halls. The university said 25 people were arrested and there were no injuries. The start of the sweep was broadcast on the Facebook page of KAEF-TV, a satellite of KRCR-TV, until police detained the reporter.

The university earlier announced a “hard closure,” meaning that people were not permitted to enter or be on campus without authorization. At 3:24 a.m., the university’s website posted a shelter-in-place order for the campus.
