The sexual assault reportedly took place on Aug. 20 in Twin Towers East, a campus residence hall, according to Marshall University spokesman David Wellman.
Both the alleged perpetrator and victim are Marshall students.
Wellman said he couldn’t provide any other information about an ongoing investigation.
“A copy of the police report will be available when the investigation is finalized,” he said.
The school sent a notice with phone numbers for local law enforcement and counselors to all students, staff and faculty who signed up for alerts — about 11,600 people — Friday morning.
