A police officer shot two men who attempted to ram a gate at the headquarters of the National Security Agency at Fort Meade, Maryland, on Monday.
One suspect is dead in the incident, and the other was seriously injured, federal law enforcement sources told WYFF.
NBC Washington reports that the men, who were disguised as women, got into an altercation with an NSA police officer at the agency gate around 9 a.m. Monday morning.
Gunfire was exchanged, and it is believed that the guard shot one, or both, of the men... At least one gun and drugs were found in the stolen Ford Escape the men were riding in.
The gate is far away from the main NSA buildings. NSA police are leading the investigation.
