(CBS) – The College of DuPage cancelled evening classes following a bomb threat Monday.

The news was posted on COD’s website, but no further information was given.

College officials said the decision was made in “light of recent events.”

John Hefferan is a member of the DuPage Community Band, which is a band for students and adults in the community. He was arriving on campus when the evacuation happened.

“When I got here, there were hundreds of people standing around.  Every building, every classroom, has been evacuated, and the campus has been shut down,” he tells WBBM Newsradio. “We don’t know if they’re just playing it safe because of what happened in Oregon, or it’s something else.”
