Authorities say a suburban Chicago teenager faces charges in an assault on a Sikh man that police are investigating as a possible hate crime.

The DuPage County State's Attorney's office announced Friday that an unnamed Willowbrook juvenile was charged with five counts of felony aggravated battery.

Police say Inderjit Mukker was driving Sept. 8 when he and the teen became involved in a "road rage incident." Both pulled over and the teen allegedly punched the 53-year-old Darien man in the face as he sat in his vehicle.

Authorities allege the teen later resisted arrested and punched an officer.

Darien police have said they'll investigate as a possible hate crime. A Sikh organization says the alleged attacker called Mukker, a U.S. citizen, a "terrorist," and said, "Go back to your country."
