By Wednesday, the University of California, Los Angeles, emerged as another key flashpoint as law enforcement, some wearing riot gear, entered the campus.

A Stony Brook University spokesperson said 29 people "including students, faculty members and others from outside our campus community" were arrested about 12:15am Thursday "for violating various legal statutes and university policies."

The spokesperson said university administrators made every effort to avert this outcome, but what began as a peaceful demonstration "escalated to include intimidation and harassment of other students and the erection of tents in violation of the University's clearly stated policy."
