Newport Harbor High School’s campus was hit by anti-Semitic fliers bearing Nazi symbols over the weekend, Newport Beach police officials said Monday, March 11.

Police received a call from the school Sunday, around 9:30 a.m., reporting at least 10 8-by-11 fliers bearing swastikas posted all over campus, said Heather Rangel, a spokeswoman for the Newport Beach Police Department.

She said the posters were not recruitment fliers representing any group. No property damage was reported.

This incident came exactly a week after a viral photo on social media showed a group of Newport-Mesa Unified high school students, some of them from Newport Harbor High, gathered around a swastika formed by red Solo cups, doing a Nazi salute.

The incident, which reportedly occurred in a Costa Mesa home during a private party, drew outrage from community members and made national news.

The school district held two town hall meetings last week. Eva Schloss, a Holocaust survivor and Anne Frank’s stepsister, paid a visit to Newport Harbor Thursday, to meet with students involved in the incident and their families.

Also on Thursday, Newport Harbor principal Sean Boulton said the Young Republicans Club on campus launched a weeks-long effort to scrub the campus clean of all hateful symbols, including swastikas etched into desks and walls.

Police officials believe the fliers were posted around campus Saturday night.

The Anti-Defamation League has reported an increase in white supremacist propaganda efforts targeting high school and college campuses, including the distribution of racist, anti-Semitic and Islamophobic fliers, stickers, banners and posters.

The ADL’s 2017-18 data showed a 77 percent increase in such incidents, nationally, from the previous academic year.
