WASHINGTON — A man has suffered life-threatening injuries after he was stabbed at the Ballston Metro station.

Metro spokeswoman Morgan Dye says the 28-year-old man was stabbed on the platform at the Orange Line station in Arlington on Sunday night around 8:40 p.m.

She says two men were taken into custody and officers found a knife.

One man, Jeffrey Kenneth Hicks, 52, of no fixed address, has been been charged with aggravated malicious wounding.

The incident on the platform started as a verbal altercation. Police have recovered 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 victim is in critical but stable condition after undergoing surgery.

The motive is unknown and Metro says investigators are reviewing surveillance video.
