(FORTUNE Magazine) – SANTA CRUZ -- Riot police using sticks and Mace ended an attempt by students to occupy the ((University of California at)) Santa Cruz chancellor's office Monday night . . . The brief . . . melee resulted in 11 arrests . . . No serious injuries were reported . . . Campus officials said the decision to use force . . . came after . . . police and UC administrators negotiated with the students, including four students who had been arrested inside the doorway after breaking through the police line. The four students were allowed ((to order)) pizza, and police agreed to allow two more women students in so those being arrested would be ''gender balanced'' with three men and three women. -- From a news report in the Santa Cruz Sentinel.
