Campus police at Indiana University have stepped up security around campus since the fifth sexual assault was reported on campus this semester.
Late Friday night, a 19-year-old student was running near Walnut Grove and McNutt Quad when she was grabbed from behind and raped, the Indianapolis' WRTV Channel 6 reported.
The woman said her attacker threatened her to be silent.
"Don't say anything. I have a knife," he said according to WRTV.
Officials across the country believe sexual assault is the most underreported crime. At Ball State, where 54.7 percent of the population is female, one forceable sexual offense was reported in 2008 and one in 2009. Four cases of sexual assault were reported in 2007, according to the Campus Security Report.
Alpha Chi Omega sorority will be discussing what to do if you are sexually assaulted on campus with a presentation from the University Police Department at 7:30 p.m. Tuesday in the L.A. Pittenger Student Center Forum Room.
Students can also utilize programs such as Rape Aggression Defense to learn how to defend themselves from such attacks. For more information about RAD, contact Sgt. Kent Kurtz at 765-285-3363.
