The incident occurred while the bus was stopped near the intersection of Georgia Avenue and Irving Street NW.
According to Metro spokesperson Sherri Ly, a man and a woman began to argue with each other while the bus was stopped. As the female passenger began to leave the bus, the man followed her.
The woman then turned and sprayed the man with pepper spray, catching several others in the line of fire.
Both the woman and the man left the scene before police arrived, says Ly.
