A Campus Safety Notice was issued by the University of Illinois Police Monday evening informing the campus community of a sexual assault which occurred Sunday.

According to the notice, the assault occurred at an Urbana apartment and the offender was someone known to the victim.

The last safety notice regarding a sexual assault on campus was sent less than two weeks ago, on Sept. 10. The reported assault occurred in a University-certified private residence hall and the offender was known to the victim.

The “red zone” of campus sexual assault refers to a heightened number of assaults during the first six weeks back on campus. Pat Wade, UI Police spokesman, said vigilance and communication is key during this time.

“We know that there is what a lot of people refer to as the red zone at the beginning of the school year where students are particularly vulnerable to sexual assault,” said Wade. “We’re very sensitive to this and that’s why we do a lot of communication with students at the beginning of the year telling them about what are some of the red flags to look for, what are some of the things they can do to either respond to or support survivors of sexual assault.”

Wade said he believes awareness as a community is crucial in addressing the “red zone” and campus assault in general.

“I think we’re doing a better job of being aware that it does happen and it happens here at the University of Illinois,” he said. “I think just being aware and talking about what we can do to prevent it, taking it upon ourselves to say something when we see certain red flags. It’s really on all of us to come together as a community and try to stop this.”
