ALBANY — Brooklyn DA Charles Hynes yesterday backed efforts to stop the $200 million-a-year auto-insurance fraud “industry,” which often stages phony accidents that leave bystanders badly injured.

“The ‘fraud industry’ has ballooned into a multimillion-dollar-a-year criminal enterprise,” said Hynes, standing with state lawmakers sponsoring a tough anti-insurance-fraud bill.

New Yorkers pay one of the highest auto-insurance premiums in the nation and accident fraud has added nearly $1 billion in premium charges since 2005, according to insurance executives.
