CHICO — In just three years, the number of reported rapes at Chico State University rose from four to 12 last year, according to the annual security report released on Tuesday.

Each year, colleges and universities are required to publish an annual security report and fire safety report by Oct. 1 under the Jeanne Clery Disclosure of Campus Security Policy and Crime Statistics Act. The crime data from the report spans from 2015 to 2017.

Nine of the 12 reported rapes were reported on campus last year, compared to six reported in 2015. All rapes that were reported on campus took place in campus residences.

Other crime numbers in the report include:

Thirteen reported on-campus burglaries in 2017 compared to eight in 2015.

Four reported robberies in 2017 compared to only one in 2015.

Six instances of stalking in 2017, up from three in 2016.

No liquor law arrests were made last year, which is significantly down from 16 arrests made in 2015.

“While the California State University, Chico Police Department has primary responsibility for providing security and law enforcement services for the University, and is generally tasked with protecting the Chico State community from all hazards and crimes, at Chico State we believe that everyone has a role to play in the prevention of violence, and have introduced some new programming to help get this message out to the community,” said Gayle Hutchinson, the university president, in the report.
