The Boston University chapter of the Sigma Chi fraternity was placed on interim suspension Friday and is undergoing investigation, officials said.

The fraternity is under investigation after allegations of possible hazing were made, said BU spokesman Colin Riley.

The fraternity is not able to operate while they are under suspension.

“The interim suspension means they’re not supposed to do any activities until the end of the investigation, and then a determination is made,” he said.

The Dean of Students office is conducting the investigation, Riley said. After the investigation is complete, investigations on the individual students will be turned over to judicial affairs.

Once all the facts are gathered, students will then be called in and be able to address any allegations that are violations of the code of student responsibility, he said.

“Allegations such as these are very concerning, particularly since we had incidents last spring,” Riley said.

“I am not going to comment on an ongoing investigation,” said Patrick Moriarty, Interfraternity Council president and College of Arts and Sciences senior.

BU’s chapter of Alpha Epsilon Pi, which was not officially recognized by the university, was suspended and subsequently shut down by the national fraternity after hazing allegations in April. Fourteen BU students were charged with hazing and hazing-related incidents, but many of those charges were later reduced or dropped.

In March, AEPi was involved in another alleged hazing incident with the Sigma Delta Tau sorority. The sorority is on suspension until January 2013.

Panhellenic Council President Linda Swift, a School of Management senior, said she declined to comment on the ongoing investigation.
