A report of a gunman on campus had Yale University hunkered down on alert Monday morning.
A university alert said New Haven police were first notified of a report of a gunman by an anonymous phone call from a phone booth.
SWAT teams were reportedly sighted at the Ivy League university, which began its November recess Saturday. Classes are scheduled to resume next week.
Most students are away on break, according to Yale Alumni Magazine.
The Yale Daily News reported that campus and New Haven police were on the scene, conducting a search.
Yale's director of emergency management and a spokeswoman for New Haven police couldn't be immediately reached for comment.
