Authorities are searching for two people who may have called in a false bomb threat at Harvard University on Saturday. An unidentified male called the Harvard University Police Department after 9:30 a.m. ET and said he was armed and had placed bombs at several buildings on campus, reported NBC affiliate NECN. Those buildings were immediately evacuated and the Cambridge Fire and Police Departments were sent to the school.
During a search of the campus, police found no one armed and no bombs. Cambridge police spokesman Jeremy Warnick told The Associated Press that they are working with FBI agents to identify two people on Twitter who claimed responsibility for the hoax call.
