The incident happened last Thursday in the 300 block of South Huntington Avenue, between Arrow Highway and Cienega Avenue.
According to the Los Angeles County Sheriff’s Department, Weichien Huang and her wife, Chen Chen Fei, got into an argument at their home when Huang attacked Fei with a sword.
Cell phone video obtained by Eyewitness News shows a woman carrying what appears to be a Samurai sword before deputies stop her in the middle of the street.
It was not immediately known if the woman caught on video walking with the sword was the victim or the suspect.
Additional video showed her walking up to the front door of a home a few doors down with blood streaming down one arm and carrying the sword in the other.
