The next time you fill up on gas, you might want a keep an eye out for crooks.
A peculiar type of theft is on the rise around the nation and some cases have been in Hawaii.
Watching the numbers run up on a gas station meter while you fill up could cost you, but it's not your bank account you have to worry about, it's your valuables.
Across the nation crooks called "Sliders" have been stealing from customers as they pump gas.
"It's terrifying, especially if you have your child in the car, it makes me angry, very angry," says Krissy Esposito.
These thieves are being caught on cameras across the country and now in Hawaii. About six cases have been reported on Oahu in the last year. About half of those involve cellphones being stolen, but other valuables are being taken as well, including entire cars.
"A person's car was stolen off the pump island because he left the key in the car and went in the store to buy something thinking that they're right there and nothings going to happen," says Barney Robinson, an independent owner of Chevron.
Reports say suspects usually circle a gas station looking for an easy opportunity. When they find it, they'll pull up and in a matter of seconds, they'll be in and out of your car without you knowing.
"Were disappointed its happening but its a reminder for people to pay attention to what's going on around them no matter where they are and what they're doing," says Robinson.
Police say the easiest way to avoid this crime is to take your valuables with you and not to leave them in the car. If you have to, you should roll up your windows, lock your doors and always be aware of your surroundings.
