Concordia University Chicago’s main campus in River Forest was on lockdown Wednesday evening while police searched for someone related to a domestic incident, officials said.
A non-student female visitor attending an on-campus event and a "male assailant" were involved in the incident, an official said. The school went on lockdown about 6:19 p.m. until shortly before 10 p.m.
Police began a search for the suspect but believe he fled the area on foot.
The female victim refused medical treatment at the scene, officials said.
“Please get to the nearest safe location, lock the doors, and await further instructions from authorities,” the university’s Public Safety Department said at the time.
A second call was made by a student to 911 to alert authorities of "loud noises" in one of the buildings on campus. That was determined to be unrelated to the incident that prompted the lockdown.
Police do not believe the suspect was armed.
