PALO ALTO (CBS SF) — A Palo Alto park restroom has been targeted with hate crime graffiti, the third time at the same restroom since May, police said.

The vandalism was discovered by a city public works crew early Wednesday morning inside the men’s restroom at El Camino Park at 155 El Camino Real.

Palo Alto police said derogatory language directed at White people had been written with black marker in several areas of the bathroom. It’s believed the vandalism happened at some point on Tuesday.
