California police have made four arrests in an alleged insurance scam that involved faking car wrecks and then filing false insurance claims.

According to The San Jose Mercury-News, the four suspects staged more than 100 collisions in California’s Bay area, resulting in more than $2 million in losses to insurers.

According to investigators, the suspects would recruit people who had policies covering bodily injury damages.

They would then stage an accident and get a chiropractor to submit bogus medical bills.
