A 19-year-old man is under arrest after being charged with assaulting an elderly man last month at the Eastern Market Metro Station.
Authorities arrested Elijah Smith Monday night without incident.
Metro Transit Police say surveillance video showed Smith punching the 69-year-old victim three times at the top of a platform escalator.
This incident happened on April 24 when the two began arguing after Smith allegedly shoved the man as they got off a train.
Smith was arrested last May for the assault and robbery of local actor Frank Britton outside of a taxi stand at the Silver Spring Metro station.
