US: DC military base on lockdown after report of armed person

“If you encounter the individual and have a safe route, RUN. If you do not have a safe route to run, HIDE. Barricade your door, turn off the lights and your cell phone ringer, and remain silent,” the post said. “If you are hiding, prepare to FIGHT.”

The Facebook notice said the “description of the individual” being sought “is a black male with a medium build carrying a Gucci Bag.” The base said officials had information that the “individual is believed to be armed.”

The 905-acre base in southeast Washington houses Air Force, Marine Corps and Coast Guard units, along with the Washington field office of the Naval Criminal Investigative Service and the headquarters of the Defense Intelligence Agency.
