A man was found walking on the tracks of the Red Line at about 8:55 a.m., just outside of the Judiciary Square stop, Metro officials said. He was not injured and not struck by a train.

The man, who was heading in the direction of Glenmont, was not authorized to be on the tracks, Metro said. A train operator assisted him back to the platform, according to Metro chief spokesman Dan Stessel.

Stessel said power on the third line was turned off briefly. As of 9:10 a.m., power was back and trains were moving in both directions.

Dan Stessel, Metro's chief spokesman, said Metro Transit Police did respond to the incident but the man was no longer on the scene. Stessel said that as part of any routine investigation, Metro Transit Police did look in the nearby Metro tunnel and found nothing.
