Oklahoma school officials have apologized to the family of a Black student who was used as the subject of a racist meme created by a classmate.

The African-American teen had been playing a part in an assembly at Chandler High School in Chandler, Okla., when one of his fellow students took the pic and shared it on Snapchat, along with an image of the Confederate flag.

“Ni**er for auction in Chandler Oklahoma,” the caption read. “Starting bid $50.”

According to The New York Post, the Snapchatter was outed by followers and suspended. Still, the Black teen’s family is livid, with big sister, Ashley Warner, sharing her disdain via Facebook.

“This is my little brother pictured in this screenshot,” she said, revealing that he was taking part in a “Positive Peers” assembly, which is meant to promote school unity.

Chandler High has released an official statement:

Chandler Public Schools experienced a deeply disturbing incident on Wednesday, April 25. During a Positive Peers school assembly, a student Snapchatted a picture of another student, who was acting out a role designed specifically for educating students regarding the importance of positive peer relationships. The student also included with the picture highlight alarming language that was hateful and demeaning. This behavior is not repetitive of Chandler Public Schools, its staff members or its students. The District has no tolerance for hateful depictions and captions regarding any student and has and will continue to address this unacceptable, despicable behavior whenever it occurs. In addition, districts officials will lean in with an even greater emphasis on educating students regarding no tolerance for actions or words that threaten, harass or bully others because of color.

No details of the district’s disciplinary action toward the student responsible for this behavior can be made available due to federal and state laws that require confidentiality. The student responsible for this behavior is not at school.

Our deepest apologies are extended to the student who was the victim of this shameful behavior by another student. As a district, we will do our utmost to support this student and the student’s family in standing against actions and speech that hurts and belittles other individuals.
