Five community colleges in the Denver area have closed or closed after threats were made against them.
Police later said the email threat received by a number of individuals at colleges early Friday morning was a hoax and a “form of defamation”.
Colorado Community College system officials say threats have been made against Arapahoe Community College, Aurora Community College, Denver Community College, Front Range Community College and Red Rocks Community College.
Aurora Community College has been put on lockdown, when classroom teaching continues but the campus buildings and grounds are secured.
Other colleges are closed for the day.
Additionally, the University of Colorado Boulder said that while there was no threat to its campus, it has canceled all classes and activities as a precaution. CU Colorado Springs said it was also closed for the day.
“We are working closely with campus security teams and law enforcement agencies to monitor the situation,” Colorado Community College System officials stated.
“Some colleges are currently on a closure protocol; we encourage students, faculty, and staff to check their institution’s website for campus-specific information.”
Police in Westminster, Colorado, say officers made contact with a person of interest on Friday and it “appears as if the threats are a form of defamation of this person.”
