NEW ORLEANS — Three days after the arrest of two Dillard University students on rape charges, police said they are investigating two more cases of alleged sexual assault on the school's campus. 

NOPD officials announced Monday there are three open investigations into sexual assaults involving Dillard students, all of which allegedly happened this month. 

Last Friday, two current students were arrested and charged with second-degree rape in connection to an incident police said happened on April 20.

In each of the cases, the suspects under investigation knew their alleged victims, NOPD officials said.

As a result, police are withholding the names of those arrested to protect the identity of the victims.

"The cases involving sexual assaults are very sensitive. Therefore, the victims and possible perpetrators will not be disclosed," one official said. 

The NOPD's investigations come after students gathered on Dillard's campus to protest sexual assault, educate about consent and support victims of sexual violence last week. 

In response to the arrests, university officials, who reported the initial allegations to the NOPD, said the school will continue to teach students about consent. 

"The University will continue to educate its students on consent, rape culture and tactical methods to protect themselves and their peers," officials said. 

All three investigations are ongoing.
