Two photos on social media showing students in Ku Klux Klan robes have prompted backlash at a Virginia high school.

Chesapeake Public School officials said they are investigating two controversial photos reportedly featuring Hickory High School students, according to news station WVEC.

Both of the photos depicting students in KKK attire were posted to Instagram. In one post, a pair of teens are seen extending their arms in a Nazi salute.

“Happy Halloween f–kers,” the caption read.

School officials wouldn’t confirm whether there would be consequences for the offensive posts.

“The school division is aware of the incident and is taking appropriate action; however, we do no comment on individual student discipline,” the school said in a statement.

Some parents, however, said that the district should not be responsible for taking any disciplinary action against the students.

“It makes me very angry,” Kitty Thompson told WVEC. “It’s up to the parents to discipline those children and tell them what’s right and wrong.”
