Xavier University police said a Black Lives Matter flag was vandalized and signs from a group that supports "extremist ideologies and hate speech" were found scattered in public areas across campus.
The incident was first reported in a notification sent to students just after 7 p.m. Saturday.
"(The Xavier University Police Department) has removed the material and is investigating the situation," officials said. "There is no indication that anyone in our campus community is responsible for posting these signs."
This is the third time over five days that Cincinnati-area universities have seen vandalism or materials left by extremist groups.
On Wednesday, graffiti was found on Northern Kentucky University's campus advertising the Patriot Front, a white nationalist hate group that formed in the aftermath of the deadly "Unite the Right" rally in Charlottesville, Virginia, in 2017, according to the Southern Poverty Law Center.
And in a statement released on Thursday, Thomas More University President Joseph Chillo said Patriot Front stickers had been found on campus property.
Though Xavier officials haven't confirmed which group left the signs, the university's student newspaper, the Xavier Newswire, posted pictures on its website of Patriot Front stickers found in different places on campus.
Patriot Front is one of 31 hate groups active statewide in Ohio and one of 15 hate groups active in Kentucky, according to Southern Poverty Law Center.
A 2019 report from the Anti-Defamation League recorded a total of 630 instances of white supremacist propaganda – including fliers, stickers, banners and posters – being placed on college campuses nationwide.
The report identified Patriot Front as being the most active hate group on college campuses, responsible for 59% of incidents of propaganda recorded.
Ohio and Kentucky were identified among the states with the highest levels of propaganda activity, according to the report.
Xavier University officials and student groups were quick to denounce the vandalism on campus.
"Hate has no home in the Xavier community," campus police said in the alert sent to students.
In a tweet posted Sunday morning, the Xavier University Student Government Association spoke out against the presence of hate speech on campus.
"We condemn white supremacy and racism in all forms," the tweet said.
Xavier police said the investigation is ongoing and anyone with information about the incident is being asked to call 513-745-2000.
