Bloodied Woman Carries Samurai Sword Through Street After Fatal Attack

A bleeding woman carrying a Samurai sword down a residential street in California flags down police in a wild video … and she’s allegedly involved in a fatal domestic dispute.

TMZ obtained footage showing a woman bleeding from multiple gashes to her leg and dragging a katana as she walks in a San Dimas-area neighborhood.

She tries to catch the police’s attention a couple times before Los Angeles County Sheriff’s Department deputies pull up and order her to drop the weapon.

LASD says they were called to this intersection on Thursday afternoon following a report of a person in need of help … and a preliminary investigation suggests a violent domestic dispute between three women.

Police say the woman in the video directed deputies to a nearby home where another woman was found suffering from cuts … and she was later pronounced dead at the scene.

Law enforcement says a third woman was also found inside the home … she appeared physically unharmed but was taken to a hospital for a “medical emergency.”
