ATHENS, Ga. (AP) — A Clarke County grand jury has indicted 16 University of Georgia students and four others who are accused of producing and distributing fake IDs.

The Athens Banner-Herald  reported Thursday that the ring was led by two roommates who provided door-to-door services. Officials say they used couriers to take customers' photos in their dorm rooms, collected personal information for the IDs and delivered the products for between $50 and $100.

Authorities say the investigation began in August 2011 and involved the University of Georgia police department and the Western Judicial Circuit District Attorney's office.

Officials say the investigation spanned Georgia, Florida, Alabama and Michigan, and more than 400 fake driver's licenses were confiscated.

UGA Police Chief Jimmy Williamson says the students may have distributed more than 2,000 fake IDs total.
