The Oregonian/OregonLive reports officers arrested a man yesterday who ran from the train.
Portland police Sgt. Pete Simpson says the assailant on the train was ranting on many topics, using "hate speech or biased language," and turned his focus on the women.
Simpson says passengers intervened and were "attacked viciously." He says one person died at the scene and another at a hospital.
Simpson says police don't know if the man has mental health issues or if he was under the influence of drugs or alcohol.
