UPDATED at 1:15 PM CST by Danny R. Butcher: The campus lockdown came after a report of a suspicious and possibly armed person on the campus. There are reports that a possible suspect has been contained, but not captured on the campus.
Two students who witnessed the suspect walking into a campus building, said they saw a man wearing kneepads and body armor, carrying a gun and Japanese-style sword.
"He had the knee pads on, like you see on a military man. It looked like he had a gun strapped on him," one of the students said.
"The police are taking care that the public are safe. We have very capable personnel actively engaged in responding to the situation," New Britain Mayor Tim O'Brien said.
The school is saying that it is not a drill. More information as we get it here.
"We will communicate when we have more info.This is not a drill," officials tweeted around noon.
A few minutes later, the university tweeted "students please stay inside your buildings until instructed to do otherwise.
Campus officials did not immediately return phone calls from Eyewitness News. However, officials kept updated the university Twitter account, reminding students to stay indoors and away going near windows.
It is unclear if anyone was injured and unknown exactly what has occurred.
