MBTA Passenger Threatens Bus Driver Officers responded to Hyde Park Avenue and Arlington Street last night at approximately 8:05pm for a man who had pulled a gun on an MBTA bus driver. The bus driver had heard two passengers using obscene language and stopped the bus to make them get off. One of the passengers approached the driver, making a gun in his waistband visible and threatening him. The suspect, Ramon Miranda, 21, of Roxbury, and another passenger then exited the bus and fled down the street. Officers in the area saw two Hispanic men walking in the vicinity that matched the description that the MBTA bus driver provided, and stopped them to conduct a threshold inquiry. Neither suspect possessed a weapon. When they were taken back to the scene, the bus driver properly identified Miranda and he was arrested on charges of Assault by Means of a Dangerous Weapon and Possession of a Firearm Without a Permit.
