WEST PALM BEACH (CBSMiami/AP) — In the continuing crackdown on staged auto accidents in Florida, authorities have charged 33 more people in the scam that is used to defraud insurance companies out of millions of dollars.

Miami U.S. Attorney Wifredo Ferrer said Thursday those charged included doctors, chiropractic clinic owners and therapists in Palm Beach and Miami-Dade counties. Ferrer says the group staged auto accidents between 2006 and 2012, submitting false insurance claims through 21 clinics that were part of the conspiracy.
