EAST LANSING — The Hannah Administration Building on Michigan State's campus was evacuated for several hours Friday due to a bomb threat.

Michigan State University Police Department received a call at 10:45 a.m. Friday about the bomb threat, spokesman Doug Monette said. The administration building was evacuated shortly after.

MSU sent out an alert at 12:39 p.m. Friday lifting the evacuation. The alert said building occupants can resume normal activities.

The Board of Trustees meeting had ended at about 10 a.m. Friday in the administration building. President Samuel Stanley, Jr., and other top officials at the university have offices in the administration building.

In northern Michigan, a wave of bomb threats prompted lockdowns at schools and hospitals across several counties. Michigan State Police's 7th District office tweeted that it believes the threats are false. The threats are in the area of Houghton Lake and West Branch.

In East Lansing, two students were charged Aug. 27 with threatening to kill Stanley. The students, Rami Souguir and Jennifer Spicer, made a post on Reddit as a joke, and took it down once they realized people were taking it seriously, Souguir's attorney, Chris Wickman said.
