UC Davis Chancellor Linda P.B. Katehi apologized to students Monday for the campus pepper-spraying incident Friday that became a rallying cry for the Occupy movement, while students once again set up encampments. "I am here to apologize,” Katehi told a crowd of about 1,000 students. "I feel horrible for what happened." She spoke shortly after some of the students who were sprayed had just described their ordeal. Katehi has put the campus police chief on administrative leave. Two officers involved in the spraying have also been put on paid leave.
