WASHINGTON (WUSA9) -- More than 100 Howard University students gathered Tuesday to protest the university's handling of investigations into two allegations of rape.

According to D.C. police reports, the two assaults date back to May 2015. Both are alleged to have occurred on campus.

In both cases, the alleged attacker is a student at Howard and a former residence hall advisor.

"It's an outrage to know that we live in a building with a rapist. I felt like my safety is gone. I don’t feel safe at all," Tori Elder, who helped organize Tuesday's protest, said.

The most recent of the two alleged rapes, according to police documents, occurred during the early morning hours of February 8 inside a residence hall.

The alleged victim in that attack broke her silence on Twitter Monday night, expressing disbelief that the man she says raped her was still at the university.

While she was posting on Twitter, another student at Howard sent her a tweet saying she was raped by the same man in his car on campus last May. A police report filed in October documents an accusation of a May rape in a parking garage at Howard University Hospital– across the street from the same residence hall.

In a statement released Tuesday afternoon, Howard said it is aware of the allegations and the administration "took immediate action as soon as we learned of this matter." The university also said it cannot comment further because of the ongoing investigation.

During Tuesday's protests, students shut down part of 4th Street NW near Howard University and could be heard chanting "No means no!"

"We’re seeing frustration. We’re seeing built up tension. We’re seeing a lack of responsibility on the administration for dealing with these issues," Ashanti Martinez, a Howard student, said.

And accusations of sexual misconduct appear to have followed the RA from California, where a woman forwarded a letter purported to be from UCLA officials to the same man – banning him from campus amid accusations he distributed revenge porn depicting a female student.

Students have released a list of demands for the university in response to the alleged rapes, including more thorough investigations for alleged assaults.

"It's not only an issue on this campus, it's like a nationwide issue that happens on many college campuses," Kayla Primes, a Howard University sophomore, said.

The full statement from Howard University is below:

Recent tweets have been posted regarding the alleged sexual assault of a Howard University student by another Howard student. The University administration took immediate action as soon as we learned of this matter. While we are not able to discuss the specifics of any ongoing investigation, we are and have been actively investigating all reports that have been made to us. These cases cannot be adjudicated through social media without compromising the integrity of the investigation.

Howard University takes matters of sexual assault very seriously. As part of our commitment to a safe campus environment, we continue to refine and enhance our Title IX protocols and procedures consistent with best practices and federal regulations. This is further supported with ongoing prevention education, collaboration, training and campus engagement.
