Dover Air Force base was placed on lockdown after a suspicious individual was reported near Building 706 at about 11 a.m.
The lockdown was lifted about three and one-halts later.
As a precautionary measure, base officials implemented base lockdown procedures and instructed all personnel to shelter in place.
“The safety of our people is our top priority,” said Col. Randy Huiss, 436th Airlift Wing vice wing commander. “We take this report very seriously and are taking the necessary precautions to investigate this matter.”
Details of the situation would be announced later, base officials indicated.
