At approximately 5 am on Friday, November 20th, students at UC Berkeley took over a campus building (Wheeler Hall), barricading themselves inside to protest the 32 percent increase in student fees and recent custodial lay-offs. Police soon arrived to close off the building and surrounding area.
The crowds of protesters you see in this video surrounding the building are joining the protest against the fee hikes and custodial layoffs as well as demanding amnesty for any student protestors facing arrest inside.
Later that evening after about a 12 hour stand off, the students inside were released in intervals and cited only for trespassing. The released students were met with cheer and applause by the outside protestors.
The clashes between police and student protestors like the one in this video occurred throughout the day and night, outside multiple sections of the building.
