(Updated at 6:05 p.m.) Reports of a suspicious person at the Ballston Metro station had police racing to the scene shortly after 5:00 p.m. to investigate.
In addition to the Arlington County Police Department, WMATA spokesman Dan Stessel says Transit Police were on the scene investigating the report of a suspicious male subject aboard an inbound train.
Few details are being released right now, but police scanner traffic first indicated the suspect may have lit WD-40 on fire inside the Ballston Metro station or inside a Metrorail car. Scanner traffic also indicates police are interviewing Metro employees at the East Falls Church station, where reports suggest the suspect may have gotten off the train.
Orange Line trains had been single tracking between Ballston and East Falls Church while police searched the station and the train, but the train in question has been released and was taken out of service. Normal service has resumed but some delays remain.
