A middle school in Colorado has promised disciplinary action against multiple students who drew swastikas on their arms after a Holocaust presentation on Friday.

The non-Jewish students at Campus Middle School (CMS) made the antisemitic gesture after viewing a film on the Holocaust, according to StopAntisemitism.

“This creates an unacceptable environment of intolerance and exclusion in our school community,” Campus principal Lissa Staal said in an email to parents, according to 9News.

She also asked parents for help in addressing the hateful behavior by students.

Staal’s letter did not specify the punishment the students will face, referring to it as “disciplinary consequences.” But Cherry Creek Schools spokesperson Lauren Snell told 9News that they “take matters like this very seriously and do not tolerate antisemitic or any hate-motivated actions or words.”

The students’ behavior will be discussed by the school during an upcoming presentation titled, “No Place for Hate Awareness Week,” according to Staal.

“We are providing advisory lessons around the negative impact and trauma that hate speech, antisemitism, anti-ableism and the use of racial slurs have on the overall culture of our school environment,” she said. “We want all our students to feel safe to be themselves at CMS, and know they are seen, respected and valued as essential members of our student community.”
