Two teenagers are in custody in connection with the severe beating of a motorist in Detroit who stopped to help a boy he hit with his car.
The two teens are suspected of being among a group of around a dozen people who attacked the driver, who remains in critical condition in a Detroit hospital.
Steven Utash accidentally hit 10-year-old David Harris after the boy stepped from a curb into traffic.
Harris was released from the hospital on Thursday.
Police say they are not planning to charge Utash in the accident.
