The victim, who is in her 50swas allegedly sitting on the corner of Eddy and Mason Street when a 20-25 year-old male suspect (the only description provided by officials) attacked her, dousing her face with bleach in the process. The two were reportedly in an argument before the assault.

The woman was taken to the hospital, where her injuries, including a loss of vision, were determined to be non-fatal. Whether her blindness is temporary or permanent has not been revealed to the public, noted Officer Grace Gatpandan of the SFPD. Authorities have not reported any motive for the assault or any arrests in the case.

Witnesses, including Tenderloin resident Ethel Hays and Harry Carr Jr., who spends time at the corner frequently, told KTVU that the victim was screaming and rubbing her eyes, while the suspect ran in another direction, before the police arrived on the scene. Anyone with information on the incident is asked to contact the SFPD.
