Anti-Semitic and racist messages and threats scrawled in black marker in a building at Cal State Northridge on Wednesday prompted campus police to boost patrols.

The graffiti was reported about 4:45 p.m. inside a men’s restroom on the third floor of Sierra Hall. The messages and symbols were written in four or five locations in the bathroom, said Cal State Northridge Police Capt. Alfredo Fernandez.
