Yale University was locked down early Monday in response to reports of a gunman on campus.

The campus was quickly placed on lockdown while authorities conducted a room-to-room sweep of campus buildings. Fortunately, most of the university's students had already left for the holidays. (Via WVIT)
Yale's campus alert system advised any students or staff still on campus to shelter in place until police had checked the area. The lockdown was partially lifted just after 3 p.m.
No shots were fired and authorities were unable to locate a suspect. Some witnesses did claim to see a gunman on campus, but WTIC reports they might have mistaken law enforcement agents for gunmen.
"Police have said in talking to at least one person, they believe that one person saw a person with a long gun on a roof and they believe that person misidentified what they now think is a law enforcement official." (Via WTIC)
No injuries of any kind have been reported. Yale's November recess began Saturday, and classes are scheduled to resume next week.
