At the University of California, Santa Cruz, students have ended a four-day occupation of the school’s main administration building, Kerr Hall. About seventy students took over the building on Thursday to protest tuition hikes. Meanwhile, at the University of California, Berkeley, forty students were arrested on Friday night when campus police entered Wheeler Hall, which the students had taken over earlier in the day. Students at UCLA and UC Davis and San Francisco State also took over campus buildings last week. On Thursday, the UC Board of Regents voted to raise tuition by 32 percent.
