Zeta Psi under investigation for alleged drugging at January frat party in London, Ont.

Investigations are underway into a January frat party in London, Ont., where several women allege they were drugged and had to be taken to hospital, CBC News has learned.

The house party at Zeta Psi house, located at 116 Mill Street in downtown London, featured an open bar. It was held to celebrate which men would be let into the fraternity, with only Zeta Psi men allowed to attend. Sorority women and their friends were also invited. 

One woman told CBC she attended the party and had four or five drinks.

The woman, who didn't want her name used for fear of retaliation, said friends eventually called an ambulance to take her to hospital because she was incoherent, something she said she has never experienced before when drinking. She also said she has no memory of much of the night, but believes a drug was slipped into her drink. 

"This has to be taken seriously," said the woman. "The only way to deter this kind of behaviour and stop it is for the school to clamp down hard on these people because if they're allowed to get away with it, if they don't see any consequences, they could potentially perpetrate this again."

The party was held four months after multiple Western University students reported being drugged during orientation week in residence. That led to a police investigation, a rally by thousands to protest misogyny and rape culture on campus, and calls that the university come up with ways to help combat gender-based and sexual violence. 

"All gender-based and sexual violence is deplorable and we won't tolerate it," Chris Alleyne, one of Western's vice-presidents, said in a statement to CBC this week. 

Alleyne added that "everyone must play a part in addressing this societal problem and preventing this kind of violence from happening at all."

The sororities and fraternities aren't officially affiliated with the university, but their members are exclusively Western students.

"I was really shocked that this happened after the increased awareness in September," the woman who believes she was drugged told CBC News. "There was the walkout, a lot of stuff on social media discouraging that kind of behaviour, and then it happens again."

While at the hospital, the woman said, she was told by a doctor and nurses there were other women from the same party, and she has talked to at least one other who believes she was drugged as well.

According to the woman, doctors at University Hospital, part of the London Health Sciences Centre (LHSC), refused to do a drug test that night to help her figure out what, if anything, may have been slipped into her drink. They refused again two days later when she went in to get a doctor's note for her professors, she said. 

The woman eventually called Western student health services. She said a doctor told her to come in right away, and tested her urine. The results showed the presence of an opioid that she said she did not take. CBC News has seen the results of the drug test.
