A woman has been blinded after a stranger poured bleach on her face in San Francisco Sunday evening, according to law enforcement officials.

The 57-year-old woman was sitting on a sidewalk in the city's Tenderloin neighborhood around 7:30 p.m. when a man in his 20s approached her and told her to move from the sidewalk, according to SFGate.

“She was sitting down when a man approached her and told her to get up and go away, and then he walked away,” a police spokesman said. “He returned back to her with a cup in his hand — she believed it was bleach — and poured it on her, causing her to lose vision.”
