Update: The Metro Transit Police Department released an update on the investigation into last night’s fatal shooting. The update, however, doesn’t say whether the suspect was armed or the nature of his altercation with a MTP officer that led to her discharging her weapon at him. Here’s the information that MTP publicly released at this time:

• At approximately 8:50 p.m., the train 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.
• At 8:52 p.m., 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.
• Metro Transit Police dispatched officers at 8:53 p.m.
• The first transit police officer arrived on scene at 8:57 p.m. Three additional MTPD units arrive prior to 9:01 p.m.
• The MTPD officers initiated inspections of the tunnels that lead into Potomac Avenue.
• Shortly before 9:10 p.m., 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.
• There were no injuries to MTPD officers.
• The identity of the decedent will be released by MPD.
• The name of Metro Transit Police officer involved has not yet been released. 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.

Authorities say that the incident is still under investigation and that anyone with information about the male suspect should call the Metropolitan Police Department at (202) 727-9099 or MTP at (301) 955-5000.

Original post:

Metro Transit Police are investigating a fatal shooting that involved one of their own officers at the Potomac Avenue Metro station last night.

According to WMATA, Metro Transit Police were investigating the westbound tunnel of the Potomac Avenue station about 400 feet from the platform after a train operator reported an unauthorized man wandering around at about 8:53 p.m.

Upon investigation, one officer fired their gun, killing the unauthorized man. At this point, it’s unclear if the man was armed if he was acting violently toward the officer. He was pronounced dead at the scene and Metrorail service to the station was single-tracking for most of the night for authorities to conduct an on-scene investigation.

The Potomac Avenue station reopened this morning with no delays as the on-scene investigation was completed. NBC4 reports that the officer involved in the shooting was put on paid administrative leave, “which is standard procedure.”
