NEW YORK (AP) — A car plowed into pedestrians on a New York City sidewalk for the fourth time in two days, hurting four people and raising the toll to nearly 2 dozen victims from the strange spate of wrecks.

Saturday's accident in Brooklyn's Flatbush neighborhood, which injured two toddlers, came a day after cars veered onto sidewalks at three locations in Manhattan, hitting a total of 18 people. Three were hospitalized in serious condition; 11 others were treated for less serious injuries.

Witnesses to Saturday's accident said the car crashed into two children at play on the sidewalk, where they lay bleeding after being hit.

A 2-year-old boy was hospitalized in critical condition, and a girl of the same age was in stable condition, police said. A 16-year-old girl and a 19-year-old woman were in stable condition.

Authorities did not say whether the women and children were related.

Police said that the 16-year-old driver ran from the scene but that officers caught up with him and arrested him on charges including reckless endangerment, reckless driving and leaving the scene of an accident.
