Ball State University sent out a public safety advisory Sunday evening saying the University Police received a report of sexual assault in an on-campus residence hall. 

The assault happened on Friday and the suspect is known to victim, according to the advisory. 

There is currently no open investigation and the victim did not request one, according to University spokesperson Kathy Wolf. 

This is now the fifth sexual assault report notice sent out in a little over a month. The university sent out a notice on Sep. 27 about a reported fondling incident in an on-campus residence hall. 

A notice was sent out on Sep. 23 after a sexual assault was reported in the 1100 block of W. Riverside Ave. A week before that, a notice was sent out about a sexual assault that was reported in the same block of W. Riverside Ave. 

Back in August, a sexual battery occurred in an on-campus residence hall, but no investigation was requested.  

These five incidents come as the university is currently under federal investigation into the mishandling of a sexual assault that occurred during the last academic year.
