Three people, including at least one student, were taken into custody at Central Connecticut State University on Monday after a security scare and lockdown that campus police said may have been caused by a student in a Halloween costume carrying a sword.
University officials placed the school on lockdown for several hours after campus police received calls about a suspicious person.
The investigators quickly traced the incident to a dormitory building where video footage showed the person entering shortly after the 911 calls.
"No weapons recovered, right now what we're doing is going back into the room to search," Chris Cervoni, chief of the campus police force, told reporters on Monday after the incident's conclusion. He said police received calls about a person who appeared to be carrying a sword and possibly a gun, but Cervoni allowed it "possibly could have been a Halloween costume."
