South Pointe High School in Rock Hill, South Carolina, was defaced with racist graffiti by vandals on Sunday with a racist , the first day of Black History month.

“It was discovered yesterday morning, and since then, it’s been eradicated,” a school staffer told Raw Story. “People are still calling because it was posted. Whoever did it, took a picture.”

The picture in question began circulating on social media, showing a large rock outside the school grounds on which someone had painted the words “Happy N****r Month” and signed it “KKK.”

It is unclear if authorities have any suspects.
