Teenager pleads guilty in April mob beating of Detroit motorist

(Reuters) - A Michigan teenager on Wednesday pleaded guilty to an assault charge and agreed to testify against others in the severe beating of a motorist who struck a child accidentally in Detroit, the second teen to do so in the case this week. The teenager, who was 16 at the time of the attack, pleaded guilty to a charge of assault with intent to do great bodily harm and prosecutors agreed to dismissal of an ethnic intimidation charge, the Wayne County Prosecutor's Office said.
