Responding to claims that police used excessive force to quell campus protests Friday, the University of California at Berkeley will conduct an investigation of the events, university officials announced Monday.  The probe will be conducted by the Campus Police Review Board, which includes representatives of students, faculty and staff. The campus police department has already begun conducting its own internal review of the events, including the use of force, officials said. The protest began after 40 people, mostly Berkeley students, occupied a campus building in response to budget cuts and a 32 percent tuition hike recently approved by California’s Board of Regents. The daylong protest in the building drew hundreds more outside, who had confrontations with law enforcement that were widely covered by national media  and broadcast on YouTube . Authorities arrested 41 people  in connection with the protests.
