Arlington County and Metro police are looking for a man who may have brandished a weapon in the Courthouse Metro location. The man is believed to have already left the station.
This information comes from police radio traffic and the incident has not been confirmed.
Update at 3:15 p.m. — The information is a bit sketchy. Police are looking for a guy fitting a certain description in the area around the Courthouse Metro station, but neither the station manager nor Metro PD ever saw the alleged weapon. It was apparently reported by a bystander.
