Thieves have found a new way to steal gas from unsuspecting people at the pump and officials are warning motorist to look for these signs.

Scammers across the nation have figured out this simple gas hose trick and it's costing unsuspecting people lots of money. Thieves are switching the hoses at the gas pumps and waiting for you to pay so they can pump and take off. The hose the thieves are using is paid for by the other person and the hose the other person uses is crossed with the unpaid pump.

While the payer is trying to figure out why no gas is coming out, the scammer is filling up their tank for free.

Officials say the easiest way to spot this scam is to double check that your hose is coming from your pump. If it is, you're good to go. If not, switch them out and alert an employee.
