ATLANTA (AP) — Authorities say a man has been arrested in a shooting aboard an Atlanta commuter train.

Metropolitan Atlanta Rapid Transit Authority officials said in a statement Monday that 30-year-old Eric Anthony Golphin is charged with aggravated assault, possession of a firearm during the commission of a crime, and possession of a firearm by a convicted felon.

Authorities have said an argument between two men on the train Saturday night at the King Memorial station escalated to gunfire and a 50-year-old man was wounded. The man was taken to Grady Memorial Hospital in stable condition.

Transit officials say Golphin's last known address was the Hancock State Prison in Sparta. MARTA spokeswoman Saba Long says Golphin has been taken to the Fulton County jail. It's unclear if he has an attorney.
