RANCHO CUCAMONGA, Calif. – A Muslim student misidentified as “Isis Phillips” in the Los Osos High School yearbook is alleging the motivation behind the mistake was racist.

But the school’s yearbook staff pointed out that another student at the school is actually named “Isis Phillips” and the innocent mistake has nothing to do with the radical terrorist group ISIS, ABC 7 reports.

Los Osos High School senior Bayan Zehif posted her yearbook photo to Facebook and Twitter yearbook on Saturday. The image identified the hijab wearing student as “Isis Phillips, 11th,” and Zehif doesn’t think it was an accident, according to The Hamilton Spectator.

“I am extremely saddened, disgusted, hurt and embarrassed that the Los Osos High School yearbook was able to get away with this,” she wrote in a Facebook post that has been shared more than 3,500 times over the weekend. “Apparently, I am ‘Isis’ in the yearbook. The school reached out to me and had the audacity to say that this was a typo. I beg to differ, let’s be real.”

The teen’s social media posts, of course, ignited a firestorm online, and the Council on American-Islamic Relations Sunday called on the school district to conduct a “thorough investigation” into the incident.

“We join with the family in their concern about a possible bias motive for this incident and in the deep concern for their daughter’s safety as a result of being falsely labeled as a member of a terrorist group,” Hussam Ayloush, the executive director of CAIR’s Los Angeles chapter, told the Los Angeles Times.

“No student should have to face the humiliation of being associated with a group as reprehensible as ISIS,” Ayloush said.

Chaffey Joint Union High School District Supt. Mat Holton told the news site Zehif was incorrectly identified as another student who is actually named Isis Phillips, and district officials contacted the families of both students to apologize.

“If they find that a student acted irresponsibly and intentionally, administration will take appropriate action,” Holton said. “The school will assure students, staff and the community that this regrettable incident in no way represents the values, or beliefs, of Los Osos High School.”

Los Osos Principal Susan Petrocelli took responsibility for the mistake and issued a public apology on Twitter.

“It is our duty to represent the students of Los Osos High School and by mis-tagging and giving the incorrect name, we failed to do so,” Petrocelli tweeted. “We should have checked each name carefully in the book and we had no intention to create this misunderstanding. It is our fault and this is absolutely inexcusable on our part.”

But Trevor Santellan, a student on the school’s yearbook staff, told the New York Daily News there was no ill intent behind the mistake, and he believes that Zehif is blowing the issue “out of proportion.”

“We have a campus of 3,200 students. Their are going to be imperfections (sic),” the student wrote in a Twitter message to the news site.

“If anything, she’s being racist against herself because she misinterpreted it and not us,” Santellan said. “Because we thought of it as a beautiful name that parents gave to a kid. She obviously doesn’t.”

Regardless, the school’s yearbook staff also issued an apology via Twitter.

“We are extremely sorry for what occurred in the Yearbook,” according to the LOHS Yearbook message. “We are currently working in coordination with the school and district office to remedy this situation.”

Holton told the Los Angeles Times that the misprint was found after the school distributed 287 yearbooks to students on Friday, and school officials are asking students to return the yearbooks to correct the mistake. The school has also halted the release of more yearbooks until the error is resolved.
