chapter's members.

 We do not believe that any AEPi members were involved in this horrible act, nor were they complicit with it,  Jonathan Pierce said in an email to the Times.

Frats at UChicago are not formally affiliated with the school but are still  subject to university policies and disciplinary procedures,  according to the college.

In a statement on Instagram, the frat said it is  deeply disturbed by the sexual assault that occurred on the night of Saturday, October 10th  and  condemn this violence unequivocally. 

 We became aware of the situation through one of our sober monitors being called over by the victim's friend,  Alpha Epsilon Pi, University of Chicago, said.

 We immediately responded and multiple members of the fraternity, including our risk manager, arrived at the scene, providing assistance to the victim.

 A member stayed with the victim until the necessary authorities arrived, only leaving after the police had asked him to do so. The party was shut down immediately following our notice of the events. 

The chapter said it  will continue to support the investigation to the fullest extent and offer our support in any way possible  and its  concern is first and foremost for the person harmed, whose privacy and dignity we ask everyone to respect. 

The frat's headquarters said it's assisting the university administration and local law enforcement with the investigation and told the UChicago chapter to pause all events while the probe is underway.

 Most importantly, all of AEPi hurts for the person who was the victim in this incident,  the national headquarters said in a statement.  No one should attend an event on any campus - fraternity-based or otherwise - and have to fear for their safety and wellbeing.
