Three male students at SIU are on interim separation from the university. Officials say they may be behind a sexual assault that happened at Neely Hall on Sunday. The victim is not a student at SIU, and she reportedly knows the three men who are accused of the crime. This is the third sexual assault reported at SIU in just over a month. Six students were arrested in connection to the other two cases. Officials say they've increased police presence at residence halls hoping to deter crime.
