Miami-Dade County is cracking down on illegal fuel sales.
Local authorities have arrested 11 men and impounded 11 vehicles as part of an ongoing operation targeting gas thieves. All 11 men were arrested on Wednesday.
Police said the men were stealing large quantities of gasoline using credit card information that was illegally obtained through electronic "skimping" devices attached to pumps.
According to police, they would store the gasoline in large bladders inside trucks and vans before eventually reselling the stolen fuel.
Authorities have warned that these makeshift gas-hauling vehicles are unsafe, likening them to "rolling bombs."
Wednesday’s arrests were part of an operation called "Fill 'Er Up," which started in February.
Police said the raids started around 10 a.m. at several locations around Miami-Dade County.
