A University of Alberta fraternity has been suspended by university administration for five years after allegations of hazing were brought forward last fall.

Campus security and the Dean of Students office launched an investigation last fall after video surfaced allegedly showing members of Delta Kappa Epsilon abusing pledges over four days in early 2010.

The video showed initiation rituals at the Delta Kappa Epsilon house last January, where pledges were swarmed, yelled at, called names and threatened with violence. A source told CTV News the footage was secretly taken during a four-day hazing event. Pledges can be seen eating raw onions and being approached with paddles.

University officials concluded hazing activities did take place.

 Dean of Students Frank Robinson announced Thursday that the group's status would be revoked for five years.

"Fraternities are an integral part of the broader U of A community. By volunteering in the community and emphasizing a balance between social and academic life, they cultivate pride in their members' university experience," said Rory Tighe, Students' Union Vice President. "I'm disappointed one group acted so selfishly, undermining and setting back the Greek reputation."

The suspension means members cannot go under the university's banner, have access to any student group privileges, or use the university's liquor and gaming licence.

In a statement posted on the fraternity's website, the group apologizes to the university saying some of their members and alumni "engaged in conduct that contravened the University's rules and the policies of our international fraternity against hazing."

"We agree that hazing has no place at the University of Alberta or in fraternity life, and we, the Delta Phi chapter of Delta Kappa Epsilon, apologize to the international fraternity, the University of Alberta, the university community, and the other fraternities at the university."

After three years, the group will be able to apply for the suspension to be lifted.

University officials say they are now working with the chapter to bring the fraternity back into a positive light.

This marks the second time the university has suspended the Delta Kappa Epsilon fraternity. The first suspension was back in 1999 for alcohol-related offences.
