Miami-Dade State Attorney Katherine Fernandez Rundle told reporters Tuesday the thieves used so-called bladder tanks that were hidden inside trucks, vans and buses. She said they sold the stolen fuel at a discount to a Hialeah fuel company, which then sold it to other customers.
The credit card thefts came using skimmers at gas station pumps.
Investigators say the ring made about $100,000 a month in fraudulent transactions.
The 11 suspects are facing racketeering, conspiracy and several other charges.
