The bomb and firearm threat on campusThursdaynight was not credible, the Department of Public Safety announcedon Fridayat around9 a.m.
The threat had made reference to the Black Justice League protest, according to University spokesperson Martin Mbugua.
After University President Christopher Eisgruber ’83 signed the modified demands of the student activistson Thursday evening, the protesters dispersed.
“The end of that event had no bearing on the credibility of the threat,” Mbugua said, adding that credibility isevaluated on a case-by-case basis.
DPS had sent a campus safety alert via email to members of the University communityon Thursdayat around9 p.m., calling the threat non-specific.
“The term is used by law enforcement agencies in cases where the details in whatever the threat is are not very specific,” Mbuguasaid.
He declined to provide further information about the nature of the threat.
Mbugua said the original threat was sent by email to an administrator, who then notified DPS. Mbugua noted that he could not specify the office or name of the administrator, nor the exact time of the incident.
To ensure security, DPS increased patrols on campusThursdaynight, according to the DPS campus safety alert.
Mbugua noted that DPS collaborated with the Federal Bureau of Investigation, the Princeton Police Department and the New Jersey State Police to investigate the incident. He declined to disclose details about the process.
“It is an ongoing investigation, and we cannot predict when or how it will be concluded,” Mbugua saidon Thursdaynight.
Princeton High School, John Witherspoon Middle School and Riverside Elementary Schoolreceived bomb threats in September. In each case, police investigations uncovered no evidence of explosive devices.
