Media reports indicated that San Francisco police were investigating after the stabbing outside the Embarcadero station. Inquiries to the department were not returned immediately.

A person was killed on Market Street outside the Embarcadero BART station in Wednesday morning and the search for the suspect caused significant delays on the BART system.
