UPDATE 3:15 p.m. EST: The lockdown and shelter-in-place orders have been lifted, according to the Yale alert system. Police have been going door-to-door on campus searching for the gunman, though authorities will not confirm whether it may have been a hoax.

"We aren't taking anything for chance and we'll continue to investigate each report," said New Haven police officer David Hartman.


New Haven Police have received an anonymous call from a phone booth in the 300 block of Columbus Avenue (between Howard Avenue and Hallock Street) reporting a person on the Yale campus with a gun. There have been NO confirmations or sightings of this person. Yale and New Haven Police are in the area. If you have information, please call 911 immediately.  The Yale Police Department advises those on campus to remain in their current location until there is additional information.

This post will be updated as further information comes in.
