LOS ANGELES — As protests resounded outside, the University of California Board of Regents approved a fee 32 percent fee increase for students attending the state's premier public schools.

The vote in a windowless University of California, Los Angeles, meeting room took place as hundreds of students and union members gathered nearby, waving signs, pounding drums and chanting "We're fired up, can't take it no more" and "Shame on you."

The $2,500 increase will push the cost of an undergraduate education to over $10,000 a year by next fall, about triple the cost of a decade ago. The fees, the equivalent of tuition, do not include the cost of housing, board and books.

"Our hand has been forced," UC President Mark Yudof told reporters after the vote. "When you don't have any money, you don't have any money."

Armed police, some with beanbag-firing shotguns, lined up behind steel barricades, watching over the protesters.

Some staff and board members were trapped in the building for up to several hours after the meeting because of the disruption outside. A van carrying regents and staff was surrounded and delayed by protesters as it tried to leave campus.

Three hours after the meeting, Yudof was escorted out by police, with protesters in pursuit shouting "Shame."

Authorities said there was one arrest.

Board members said the 229,000-student system had been whipsawed by years of state budget cuts, leaving no option other than turning to students' wallets.

Yudof has said the 10-campus system needs a $913 million increase in state funding next year, in addition to higher student fees.

State Assembly Speaker Karen Bass, a Democrat who sits on the board, said she would push for higher taxes, possibly on higher-income residents, to finance education. The state could face $20 billion shortfalls during each of the next five years.
