Students were immediately evacuated to New Haven Green, a privately-owned park located in the downtown district of New Haven.
According to the university's newspaper, Yale Daily News, the threats referred to structures on the Old Campus and multiple surrounding buildings.
The University Theater, Jonathan Edward College, the Yale Art Gallery, Vanderbilt Hall, Bingham Hall, Welch Hall and the Grace Hopper College had all been evacuated, per a 2:35 p.m. Yale alert.
The Old Campus has been reported as being currently blocked off to traffic and pedestrians.
Tweeted video at the scene shows first responders blocking intersections near buildings, as evacuated students stand nearby.
Additional video shows city streets that were shut down, as first responders secure the area from potential threats.
Harrison Bushnell, 23, a student at Yale University, was in class inside one of the threatened buildings when the school staff was alerted and everyone in the building was quickly evacuated without explanation. “They didn’t say why, they just said it was an evacuation,” he said according to the Yale Daily News.
“I was just in a session about a class that’s going to be offered in the spring, and then they came in and said we all had to go to the North Green.”
Nicholas A. Christakis, a professor of Social and Natural Science at Yale, shared the Friday Yale Alert, while comparing it to a past experience at Harvard University and suggesting that when "something happened like this, it was usually an undergraduate student who wanted to avoid an exam." Pranks of this nature will result in the student being charged with a federal crime, if they are caught. "I really hope it's not something like that," Christakis remarked.
