Columbia, Brown, and Cornell are investigating bomb threats

• Several Ivy League universities reported bomb threats on Sunday.
• Columbia, Brown, and Cornell University evacuated buildings and investigated threats.

Several Ivy League universities evacuated buildings on Sunday following bomb threats.

In a statement, Columbia University said the New York Police Department was investigating bomb threats made at several university buildings around 2:30 p.m. this afternoon.

The NYPD said they received a call about a suspicious device but said the call was "unfounded."

A Columbia spokesperson told Insider in a statement that the investigation found the threats to be not credible and the buildings that were evacuated have since been reopened.

In a statement to Insider, Brian Clark, a Brown University spokesperson, said the university's Department of Public Safety evacuated several buildings near the university's College Green at around 4:30 p.m. after receiving a bomb threat by phone.

Police officers investigating found "no evidence of a credible threat" and evacuated buildings have been reopened, Clark said.

"After comprehensive searches by both Brown University and Providence Police officers, the university's Department of Public Safety issued an all-clear update for the Brown campus," Clark said.

At around 3:00 p.m. on Sunday, Cornell University sent out an alert for a bomb threat on the Ithaca campus.

Cornell called for areas in or nearby the Law School, Goldwin Smith, Upson Hall, and Kennedy Hall to be evacuated.

The alert was still in place as of 5:30 p.m. on Sunday and the university said local and state law enforcement agencies were assisting Cornell Police in an investigation.

As of 7:30 p.m., a Cornell spokesperson told Insider the investigations found that the threats were not credible and buildings have reopened.

It's unclear if any of these threats are connected.

Sunday's bomb threats also come two days after multiple buildings on Yale University's campus were evacuated following a bomb threat, the Yale Daily News reported.

The New Haven Independent reported that police received a call "stating 40 bombs" were placed in various buildings on campus at around 2:00 p.m. on Friday. Officials issued an all-clear later that night.
