Students, professors and staff at the University of Wisconsin Law School were told to leave the building Wednesday just before noon because of a possible gun threat.
Police received a call at 11:26 a.m. that there was a man with a gun in the Law School Library, which is in the law school building, 975 Bascom Mall. Shortly after that, University of Wisconsin-Madison Police Department, through a campus-wide alert, told students to avoid the area and that officers were on the scene. Law school officials also sent emails to faculty, staff and students instructing them to leave the building.
The entire law school building was evacuated and searched. At 12:05 p.m., the officers finished and found no one in the building with a weapon.
Law school officials and campus police sent an alert about half an hour after the first one, saying the threat no longer existed.
The campus police department had received the call from the library, and there were no confirmed reports of anyone seeing a weapon in the library, according to a press release issued later that afternoon by campus police.
An investigation is ongoing and no further information is available, according the the release.
A previous version of this article misstated that law school officials indicated that police determined the man had no gun. They had indicated police found no gun in the building.
