Penn State has placed Acacia fraternity on interim suspension while its Office of Student conduct investigates an undisclosed incident that allegedly occurred at an unregistered social event.

According to a university statement published on Friday, the fraternity’s interim suspension began on Monday, April 11.

While operating under interim suspension, Acacia can’t host any social functions as the investigation continues. Penn State said Acacia’s national organization is aware of the investigation and is cooperating.

“The interim action is intended to minimize continued risks while a full investigation is conducted,” the university wrote in a statement.

Penn State said it may levy additional sanctions against Acacia depending on the outcome of the university’s investigation.
