All classes at Holyoke Community College have been canceled Monday because of a threatening note found on campus this morning. The exact contents of the note have not yet been disclosed.Erica Broman, HCC Vice President for Institutional Development tells the media a “specific and threatening” note was found in the school’s Kittredge Center. Campus police were called, who in turn notified Massachusetts State Police from the Hampden County District Attorney’s Office. The campus was originally scheduled to be re-opened around 10:00 A.M., but Broman says school officials decided to close the campus all day to ensure police would have time to investigate. Students received text messages, e-mails, and phone notifications to let them know about the situation. Broman says that HCC is hoping to resume classes Tuesday.
