Racist graffiti on bathrooms at California High School in San Ramon, Calif.

*Racist graffiti scrawled on the walls of a Bay Area high school bathroom have students outraged and the local police investigating.

According to NBC Bay Area, the N-word was written in the girls’ restroom, and the words “whites” and “colored” were scribbled above the urinals in the boys’ rest room at California High School in San Ramon.

A student came forward to take credit for graffiti in the boys restroom. School officials have not revealed how that student would be punished.

Police and school officials said those found responsible for the graffiti could face criminal charges and expulsion from school.

When 17-year-old Cal High student Alanah Winston saw the racist graffiti in the girls bathroom on Monday, it made her extremely uncomfortable.

“I deal with racism on a daily basis as a kid of color, as a minority,” said Winston, one of about 100 black students at the school of 1,200.

“And then just to see blatant hatred written there for you to see,” she added, has stripped away that feeling of safety.

When Winston approached school administrators to do something, she wasn’t happy with their response.

“I was somewhat dismissed,” she said.

San Ramon Valley Unified School District spokesperson Elizabeth Graswich told NBC Bay Area that their initial report of the graffiti in the boys restroom last week was taken very seriously, and that school officials began an investigation immediately. She said the only evidence found from the boys restroom graffiti were photos.

“It was a challenging one to investigate because it was shared via social media, with no indicators other than that they said it was at California High School,” Graswich said.

Winston said she just wants a resolution.

“I just want action to be taken,” she said. “I want this to be prevented.”
