A campus police spokesperson confirmed to CBS News that students are being asked to seek shelter.
The university has also officially stated that there has been a report of a suspicious person carrying a gun on campus.
CBS Affiliate WFSB was told by numerous students of sightings of a masked man with a gun, or a man wearing camouflage and carrying a knife, entering a dormitory.
Jordan Governale, a 20-year-old junior from Farmington, 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.
A minute later he said he saw police responding.
“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. “It’s pretty scary. It’s pretty strange, unexpected.”
Governale said he did not hear gunshots.
Students have reportedly barricaded themselves inside their dorm rooms at James Hall.
CBS Affiliate WFSB reports the heavy police presence on campus included SWAT teams and police dogs. The station said three SWAT teams are conducting a sweep of the area.
Lt. J. Paul Vance, a state police spokesman, says university police asked for assistance related to a report of a suspicious person.
New Britain Mayor Tim O’Brien told the media that there are no reports of injuries at this time.
More than 12,000 students attend the university, which has a 182-acre campus.
According to the station, HALS Academy and Holmes Elementary School in New Britain are in a modified lockdown due to the emergency on the CCSU campus.
