The San Francisco Police Department say that they have successfully apprehended the man who allegedly drove off after slamming into a woman and child as they walked in a crosswalk Monday night.

According to SFPD, a 68-year-old woman and a 13-year-old girl were in a crosswalk on the 300 block of Williams Avenue at 6:40 p.m. yesterday when they were hit.

The driver, who had yet to be named by SFPD and is described only as a 55-year-old man, struck the women with his black two-door Infinity I30, then "fled the scene," police say.

The older woman was left with a broken knee, and the child suffered head trauma. Both were rushed to an area hospital, and are expected to survive.

The driver was "later apprehended," police say, but did not offer any additional details on the collision or investigation as of publication time.

Update: The SF Examiner reports that the arrested man is named Richard Bilworth, that he was caught in a backyard at Bridgeview Drive, and that "police suspect [he] was under the influence at the time of the collision," and "was booked into county jail and faces felony DUI and hit-and-run charges."
