Students from Hickory High School in Chesapeake, Va. dressed as members of the Ku Klux Klan and posted photos of it on social media, prompting an investigation by the school.

The photos surfaced on Instagram earlier this week, showing teens wearing white sheets and hoods and doing Nazi salutes. One post reads “Happy Halloween [expletive]."

A student from Hickory reposted the images on Twitter and wrote, “Kids at my school think it’s funny to dress up as the kkk hate for hickory is unreal.”
