The University is investigating allegations that members of the Sigma Delta Tau chapter hazed new members.

In a joint statement, Associate Dean of Students Tim Miller and Gabriel Slifka, director of the office of Student Rights and Responsibility, said the University is working with Sigma Delta Tau’s national organization to “conduct a prompt and thorough inquiry” of the hazing allegations, which violate University and Sigma Delta Tau’s national policies.

University officials declined to provide any further information, such as details of the alleged hazing incident, how many members were involved and how the University learned about the incident.

Debbie Snyder, executive director of the Sigma Delta Tau national sorority, said the national officials are on campus this week to work with the University and will be “talking to members of the organization to do the investigation.”

“We’re working with the university administration on that in a combined effort to ascertain what happened,” Snyder said.

She declined to provide any other details, such as a description of the alleged hazing incident, how many members were involved or how the national organization could punish the chapter.

Liel Azoolin, the chapter’s president, said the national sorority told her she could not speak to the media.

“I am actually not allowed to comment on anything,” Azoolin said.

The chapter last found itself in trouble with its national organization in November 2005 when national Sigma Delta Tau officials suspended the chapter following what a University spokeswoman then described as “risk management violations.”
