Authorities say a man was stabbed and seriously injured at the Ballston Metro station.
Metro spokeswoman Morgan Dye says the man was stabbed on the platform at the orange line station in Arlington on Sunday night. She says two men were taken into custody and officers found a knife.
Metro says the man suffered life-threatening injuries when he was stabbed in the stomach and arm and the station manager tended to him until paramedics arrived. The motive is unknown and Metro says investigators are reviewing surveillance video.
