WASHINGTON—A military base in the nation’s capital was locked down for about two hours Friday, after an armed man ran onto the grounds during a local police investigation of gunshots on the streets surrounding the base.
A statement from Joint Base Anacostia-Bolling said the man’s firearm was discovered after the intrusion, and the intruder himself was detained around 2:45 p.m. during “a thorough sweep of the installation.”
