Dozens of protesters are occupying the main administrative building at University of California, Santa Cruz in the third straight day of protest over fee hikes and cuts to campus services.
School officials said Saturday they wouldn't negotiate with the demonstrators until obstructions at the occupied Kerr Hall are cleared.
Protests began Thursday after the university system's regents approved a 32 percent fee hike at a meeting in Los Angeles.
On Friday, 41 people inside UC Berkeley's Wheeler Hall were arrested after occupying that building for most of the day.
Thirty to 50 protesters took over UCLA's Campbell Hall on Thursday, and more than 50 students were arrested during protests at UC Davis.
