Per San Francisco Police Officers, trains were held out of the station as they searched for a male suspect who was said to have been involved in an armed robbery on a city street. The suspect was reportedly on the #1 trackway and headed toward the Embarcadero Station. A combination of BART and San Francisco Police officers searched both trackways between the Montgomery and Embarcadero stations, but did not locate the suspect; two other involved suspects were detained, and a handgun recovered, by San Francisco Police Officers in their jurisdiction. Trains were delayed for approximately 45 minutes. TSOC notified (“Jeff”).
