A driver who beat a pedestrian for making contact with his car remains at large today, following a SoMa confrontation that sent the victim to the hospital.

Police say that the 50-year-old male pedestrian was crossing the street at the intersection of 10th and Harrison Streets at 7 p.m. Tuesday when the confrontation occurred. According to the San Francisco Police Department, the victim crossed in front of a brown 4-door sedan that apparently extended into the intersection, "and tapped on the vehicle."

The driver, a man in his 20s, hopped out of the car and chased the pedestrian down "and punched him, knocking him to the ground," police say.

The driver then fled in an unknown direction, leaving his victim injured on the ground.

The pedestrian was transported to San Francisco General Hospital for treatment of injuries police say are not life-threatening. The suspect and his brown car remain at large, and neither have been tracked down as of Wednesday afternoon.
