Central Connecticut State University ordered students and faculty were ordered to stay inside buildings, lock the doors and lower window shades after emergency calls reported an armed man walking around the campus.
Police brought the suspect, who was wearing camouflaged pants, a black mask, an orange shirt, a tactical vest and was carrying what appeared to be a sword and a handgun, into custody.
No one was hurt and no shots were fired.
CCSU Police Chief Chris Cervoni says the investigation is not ruling out some kind of a hoax, and has confirmed that no weapons were found. No charges have been filed, but police are also interviewing two other people in the incident.
Two students who claimed to know the individual told the Hartford Courant the entire thing was just a misunderstanding.
“For Halloween he was a samurai,” 18-year-old Matt Hecker said. “As soon as I heard the description, I said ‘That’s [the man], what’s he doing.””
Another student, Jon Cullin, 19, said, “That’s exactly what he wore for Halloween.”
No charges have been filed in the incident, which caused the cancellation of classes and a massive police and SWAT mobilization.
