HAYWARD — A passenger was fatally stabbed Tuesday afternoon aboard a BART train, forcing the closure of the South Hayward station while authorities sought and arrested a suspect and investigated the scene.
In a press conference, interim BART police Chief Ed Alvarez said dispatchers learned of a fight between two males in their 40s just after 1 p.m. aboard a train that had just departed the Bay Fair station in San Leandro.
