Two University of Wisconsin-Madison students say they were drugged at off-campus fraternity houses, with one also reporting a sexual assault … another troubling set of allegations involving Greek life.

UW-Madison said both students came forward Sunday with separate allegations. In one case, a student said they were drugged Saturday night at a frat house and inappropriately touched at two different fraternity houses.

The other student said they were drugged at an off-campus frat Sept. 17 and later sexually assaulted at a residence hall. The university says the victim and suspect know each other.

One incident was reported to Madison police, while the other was not … meaning there is no active criminal investigation in that case.

The allegations come just days after two leaders of an off-campus Alpha Epsilon Pi chapter were arrested on hazing and disorderly conduct allegations after cops say they found about 30 partially clothed 18-year-olds in a basement, some with visible injuries.

And the reports come as another fraternity case remains under the microscope … the alleged Cornell gang rape.

As TMZ previously reported, a Cornell student accused seven Chi Phi members of drugging and gang-raping her in October 2024 … she she claims one of them sent a Snapchat message advertising “free p***y.”
