Columbia University and other Ivy League institutions evacuated facilities in response to bomb threats.
Columbia University evacuated two campus buildings Sunday after receiving a bomb threat. Columbia was one of four Ivy League colleges threatened over the weekend.
Cornell University and Brown University officials confirmed Sunday that areas of their campuses were evacuated following bomb threats — only two days after Yale University was forced to temporarily close parts of its campus following an earlier threat.
According to WCAU-TV reporter Tyler Dumont, Brown University was cleaning out certain campus buildings "after a bomb threat" in the latest incident.
Cornell had done the same thing just a few hours earlier.
"Cornell ALERT," the university tweeted. "Law enforcement is on-scene investigating a bomb threat on the campus. A security perimeter has been established. Continue to stay away from the core campus."
School officials had stated in a tweet that multiple buildings had been evacuated.
"Alert for the Ithaca campus: Avoid the central campus," the university tweeted. "Withdraw from places within or adjacent to the Law School, Goldwin Smith, Upson Hall, and Kennedy Hall."
"We will share additional information when it becomes available," the message stated.
Authorities have made no connection between the threats and the Ivy League schools.
Yale University received a bomb threat on Friday, according to a university official.
Columbia spokeswoman Caroline Adelman said Sunday that the institution had also received a threat.
"We were contacted solely through text," Adelman told The Post. "It makes reference to two evacuated buildings and cautions people to keep away."
She identified the structures as the Carmen and Lerner.
