City Desk has obtained video that sheds light on what happened after, on Dec. 23, some Metrorail customers found themselves sitting ducks as muggers terrorized them on an Orange Line train. The chaos took place between the Stadium-Armory and Minnesota Avenue stops. The footage shows the muggers escaping from a Minnesota Avenue exit. It also shows two of them socking a passerby for no apparent reason as they leave. The shocked patron shoves his hand inside of his bag as though he has a weapon and follows his assailants for a moment.
