Classes were cancelled at Central Connecticut State University on Monday after a potentially armed man was spotted on the campus prompting a university lockdown.

A campus emergency alert was issued Monday afternoon at the public university in New Britain, Conn. after a man who may have been armed was seen entering one of the halls, according to police sources. Officials at CCSU also urged students to remain inside their building as police officers searched the campus grounds up until about 3:00 p.m. Around that time, New Britain Mayor Tim O'Brien confirmed that the suspect was brought into custody.

University spokesman Mark McLaughlin said, "Somebody was seen either with a gun or was thought to have a gun."

Jordan Governale, a 20-year-old junior at the school, said he walked by a man carrying a backpack and with a sword and sheath strapped to his back. The man was wearing a mask, camouflage pants, knee pads and a vest resembling body armor, Governale said.

"At first I thought it was a Halloween costume. But after I saw the cops I thought it was some sort of threat," he said, reports the Associated Press. "It's pretty scary. It's pretty strange, unexpected."

More than 12,000 students attend the university outside Hartford, which has a 182-acre campus.

Mayor O'Brien has been on the campus and said there are no injuries to report.

According to the Hartford Courant, a man was seen being led away in handcuffs around 2:30 p.m. State police had been talking with a man who had been boxed into a dorm room in James Hall, a source told The Courant. There had been no hostile act, the source said.
