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 reported in stable condition. Two young women, 16 and 19, are in stable condition.
Police say the 16-year-old driver ran from the scene, but that officers caught up with him and arrested him on several charges.
