A handful of racist fliers advertising a white supremacist website were found posted around Cal State University Long Beach on Sunday and Monday, according to campus officials.

The fliers, which featured swastikas and anti-Semitic slogans, were discovered at three different buildings over the span of two days, authorities said.

Police are investigating the postings as vandalism because whoever hung the fliers used an adhesive spray to attach them to the campus Multicultural Center, the Molecular and Life Sciences Building, and Liberal Arts 1 Building.

This is the third time this year that racist fliers have appeared at the university, according to authorities.

“It’s certainly safe to say that there’s been an uptick in the distribution of illegal, hateful posters on campus,” said Terri Carbaugh, a spokeswoman for the university.

On March 13, authorities found a flier near the Molecular and Life Sciences Building that featured a swastika and with a phrase disparaging Jewish people, according to Carbaugh.

And in February, campus officials removed fliers from the library and other locations that advertised the white nationalist group Identity Europa.

The fliers posted this week and in March advertised a different group, Aryan Underground, which describes itself on its website as “a National Socialist and Fascist organization dedicated to absolute resistance against the Zionist Occupied Government.”

In each case, the fliers were posted in violation of campus rules and quickly taken down, according to Carbaugh.

However, police asked any students or staff who find more fliers not to remove them or even touch them.

“Contact (police) immediately so that we can attempt to remove them and save potentially critical evidence,” the department said in a statement.

Authorities aren’t sure if the person or person behind the posters is associated with campus in any way.

“While, it remains unclear who is behind these malicious and anti-Semitic efforts, campus police are encouraging people to come forward if they know anything,” Carbaugh said.

She added that campus president Jane Close Conoley “is doing everything in her power to assure students, faculty and staff that everyone is welcome, and safe, at The Beach.”

Police asked that anyone with information contact Det. Christopher Brown at christopher.brown@csulb.edu or (562) 985-8938.
