(Reuters) -The U.S. Naval Academy in Annapolis, Maryland, was placed on a security lockdown on Thursday while military personnel and local law enforcement investigated reports of threats to the installation, the Navy said on the academy's Facebook page.
There was no immediate official word on the nature of the reported threat. But Fox News, citing multiple sources inside the academy, said a former midshipman who had been expelled from the school had returned to campus armed with a weapon.
