Authorities are investigating vandalism at a University of California Davis dorm room occupied by a Jewish student.

The student this week found a two-inch swastika carved into her dorm room door. The freshman student, who asked not to be identified, told television station KXTV that she was scared and confused.

In letter sent Friday to students and faculty, UC Davis Chancellor Linda P.B. Katehi says the university will not ignore deliberate acts that demean and threaten others.

Campus authorities are searching for the vandal.
