Brown, Cornell and Columbia University evacuated parts of their campuses on Sunday after receiving bomb threats, just days after another bomb threat was reported at Yale University. It is not clear if the threats are connected, and no suspect has been publicly connected to any of the calls, which were all later deemed to be false threats.
Columbia said it issued “a campus-wide emergency alert” after receiving threats to school buildings. The New York City school warned students to avoid the area while police investigate, but later said the threat was deemed “not credible” and it was safe to return.
