ITHACA, N.Y. (WENY) -- The Interfraternity Council at Cornell University has temporarily suspended all fraternity parties and social events after a reported sexual assault and multiple reports of women being drugged. 

Campus police issued two alerts about an alleged sexual assault that took place on Sunday, Nov. 6. It reportedly happened between 2:30 a.m. and 4:30 a.m. at an event in the 100 block of Thurston Avenue. 

Cornell police additionally issued alerts regarding at least four alleged reports of drug-laced drinks that occurred over the last several weeks. According to police, the drinks were laced with Rohypnol, more commonly known as “roofies.” It is not clear if the druggings and sexual assault are related. 

According to a university-issued statement to students, all incidents reportedly happened at off-campus fraternity-affiliated houses. All social events will resume once the school is confident that they can happen safely. 

Ithaca police released a statement on Monday that said they are currently investigating the incidents. Anyone with information regarding any incident is asked to contact the Ithaca Police Department at their dispatch line at (607) 272-3245, or their tipline at (607) 330-0000.
