( CNN ) -- A Harvard University student was named Tuesday in a criminal complaint alleging he was responsible for bomb threats that led school officials to delay some final exams , including his , that had been scheduled for Monday . Eldo Kim , 20 , of Cambridge , allegedly e-mailed bomb threats at about 8:30 a.m. Monday to offices associated with Harvard , including the Harvard University Police Department and the Harvard Crimson , the student-run daily newspaper , according to the five-page complaint . The subject line in each of the messages read `` bombs placed around campus '' and cited `` shrapnel bombs '' in four buildings on the school 's main campus in Cambridge . `` 2/4 . guess correctly . be quick or they will go off soon , '' they said . The Harvard police called in the FBI ; the Bureau of Alcohol , Tobacco , Firearms and Explosives ; the Secret Service ; the Cambridge Police Department and the Boston Police Department along with numerous other first responders , including the Cambridge Fire Department . The buildings were evacuated and swept by bomb technicians and hazmat officers , and access to Harvard Yard was restricted to students with Harvard IDs , according to the Harvard Gazette , the school 's official news website . Shortly before 3 p.m. , long after Kim 's exam had been canceled for the day , officials concluded that the threats were a hoax and reopened the buildings . `` Those who missed their exams due to the evacuation should be in touch with administrators about a makeup date or other arrangement , '' the Gazette said . The e-mail messages had been sent through a service called Guerrilla Mail , which creates temporary and anonymous e-mail messages , according to the complaint . And the person had used a product called TOR , which assigns an anonymous Internet Protocol address that can be used to hide the identity of the sender , it added . But the sender failed to do that , according to the complaint . `` Harvard University was able to determine that , in the several hours leading up to the receipt of the e-mail messages described above , Eldo Kim accessed TOR using Harvard 's wireless network , '' it said . The Crimson identified Kim as a sophomore . An FBI agent and an officer with the Harvard University Police Department interviewed Kim Monday night at his campus residence , where he `` stated that he authored the bomb threat e-mails '' and said he had acted alone , the complaint says . `` According to Kim , he was motivated by a desire to avoid a final exam scheduled to be held on ( Monday ) , '' the complaint said . He is to appear Wednesday in U.S. District Court before District of Massachusetts Chief Judge Judith G. Dein . In a statement , school officials said they were `` saddened by the details alleged in the criminal complaint '' but had no further comment . If convicted , the student could face a maximum of five years in prison , three years of suspended release , and a $ 250,000 fine .
A Gazette sophomore is accused of sending phony e-mail threats to avoid final exam . Kim , 20 , allegedly e-mailed the threats half an hour before his exam was to begin . His exam and others were canceled for 20 after buildings were evacuated . Eldo Kim 's first court appearance is slated for 20 .
