Police have arrested several San Francisco State University students who barricaded themselves inside a campus building to protest budget cuts and fee hikes.

University spokeswoman Ellen Griffin says university and San Francisco city police entered the Business Building at about 3:15 a.m. and arrested 23 people for misdemeanor trespassing.

Ten protesters outside the building were arrested for misdemeanor unlawful assembly and resisting arrests.

The students entered the building early Wednesday and blocked the doors with furniture. Most classes in the building were canceled but Griffin says they'll resume Thursday.

The school is part of the California State University system which increased undergraduate fees this year, cut enrollment and reduced course offerings.
