Officers intercepted a S.F. Airport train at the Pleasant Hill Station to investigate a report of a male subject that evaded fare at the Pittsburg/Bay Point Station. While searching the train for the subject it was reported that a male subject was harassing a passenger aboard the same train. The victim, who did not wish to file a complaint, identified the male subject (Morikawa, Yaiszu 49 y/o, Sacramento) as the subject that was harassing him. A records check revealed an active stay away order from BART. The subject was issued a citation for fare evasion, as he was on the train without a valid ticket, and booked at the Martinez Detention Facility for the court order violation.
