At approximately 8:53 p.m., Transit Police say they got a call about an "unauthorized person" in the tunnel near the Potomac Avenue station. A police source tells FOX 5's Paul Wagner that the initial radio dispatch said the man had "sticks in his hands."
During the course of the investigation, one of the officers at the scene encountered the man in the westbound tunnel, and shots were fired by the officer. No officers were injured in the incident.
On Friday, Metro Transit Police released the following timeline of events from Thursday night:
8:50 PM: The operator of a Franconia-Springfield-bound Blue Line train notified the Metro Rail Operations Control Center of an unauthorized subject in the tunnel between Stadium-Armory and Potomac Avenue stations.
8:52 PM: The reporting train was secured at Potomac Avenue and the track was taken out of service. Third-rail power was de-energized by the Rail Operations Control Center.
8:53 PM: Metro Transit Police dispatched officers.
8:57 PM: The first transit police officer arrived on scene.
JUST BEFORE 9:01 PM: Three additional MTPD units arrived. The MTPD officers initiated inspections of the tunnels that lead into Potomac Avenue.
JUST BEFORE 9:10 PM: A responding MTPD officer encountered a male subject in the westbound tunnel approximately 400 feet east of Potomac Avenue Station. During that encounter, the MTPD officer discharged her department-issued service weapon, resulting in fatal injuries to the male subject.
The Metropolitan Police Department collected evidence and processed the scene, which is standard. That evidence is being turned over to the U.S. Attorney's Office for review.
The Metro Transit officer's name has not been released, but she is a veteran officer with more than 10 years of service. As is standard protocol, the officer involved has been placed on paid administrative leave during the review of use of force.
The incident remains under investigation. Anyone who may have witnessed the incident, or may have seen the man in or around Potomac Avenue Station, or the adjacent stations of Eastern Market or Stadium-Armory, is asked to call Metropolitan Police at (202) 727-9099 or Metro Transit Police at (301) 955-5000.
Potomac Avenue Station was closed from the time of the incident until the MPD investigation was completed during the overnight hours. From 9 p.m. until midnight, Blue, Orange and Silver line trains operated through the station without stopping using a single track. The station reopened for normal service this morning.
