CSUSM officials said the incident was reported to campus police Friday, but the incident allegedly took place between the night of September 12 to September 14 at the Quad residential hall at 200 Barham Drive.
The suspect had apparently been invited to a party at the residence hall where he met the victim.
University officials could not provide information as to whether drugs or alcohol were involved, or why the incident was being reported three weeks after it happened.
This is the second alleged sexual assault to take place in the Quad residence hall. A crime alert was issued Thursday, September 25 after a man allegedly sexually assaulted a female student he met at a party in the same housing complex. In that case the suspect was not a student at CSUSM.
Students living at the Quad said both incidents and descriptions of the suspects sound similar.
In the latest reported sexual assault, the suspect is described as an 18 year old black man. He's about 5-feet, 8-inches and weighs 170 pounds. He is also described to have short black hair and brown eyes. Campus officials said the man is believed to be a resident of Orange County and not a student at CSUSM.
