An elderly woman was struck by a stray bullet Tuesday while eating at a restaurant in downtown San Francisco, according to police and local reports.

Police on Tuesday responded to reports of a shooting on the 2000 block of Market Street just before 5 p.m. PT and found both a 22-year-old man and 85-year-old woman suffering from non-life-threatening gunshot wounds, according to the San Francisco Police Department (SFPD).

"It's unclear if it was glass or the bullet actually grazed her," MacNiven told the outlet. "We have been in contact with her and she is in good spirits as of yesterday."

Authorities transported both victims to a nearby hospital while officers on the scene interviewed witnesses.

Police learned that a group of people had gotten into a physical altercation across the street from the restaurant. One person in that group produced a gun and "fired into the crowd that was fighting," according to the SFPD.
