The Jewish fraternity at Emory University holding their Yom Kippur holiday events when someone spray painted Nazi emblems on their home.

Yom Kippur is one of the most holy days in Judiasm, a time when Jews fast and focus on repentance for their sins over the past year.

“We are outraged at the insensitive display of prejudice that occurred at the Alpha Epsilon Pi house at Emory University. We are working alongside Emory to ensure that intolerable acts of hate, such as this, will never occur again. We are thankful for the community around us that has shown tremendous support throughout this time,” the fraternity told Business Insider.

Police are investigating the incident and have increased patrols around the area of the fraternity in case the assailants choose to come back for a second attack.

Emory University President James Wagner e-mailed students and faculty condemning the event.

“On behalf of our community, I denounce this abhorrent act. It is an offense against a Jewish fraternity and the Jewish members of our community, and it is a repugnant, flagrant emblem of anti-Semitism. It is also an offense against the entire university. Among the many pernicious things the swastika symbolizes, in the last century it represented the most egregious and determined undermining of intellectual freedom and truth-seeking. In short, its appearance on our campus is an attack against everything for which Emory stands,” he wrote.
