Occupants of Jadwin Hall and Icahn Laboratory have been released to go home as the assessment continues on Princeton's campus following a report of an unsubstantiated bomb threat received at the nearby New Chemistry Building construction site.

The University's Department of Public Safety has determined that there is no imminent threat, but as a precautionary measure the University evacuated Jadwin and Icahn because of their proximity to the site.

The University community was notified that workers were evacuated from the New Chemistry Building construction site at 11:20 Friday morning. The University began evacuating Jadwin and Icahn just before noon and asked evacuees to assemble inside nearby public buildings, such as Frist Campus Center and campus libraries.

Jadwin and Icahn house classrooms, laboratories and academic department offices. Users of those buildings have been advised to visit the University home page for updates over the weekend. The buildings are located in the southern part of Princeton's campus off Washington Road.

Township Police and area law enforcement agencies, along with the Department of Public Safety, are continuing to investigate.
