Rhodes says there may be 30 people, usually working in a group of three, hitting gas stations around the area. He says the group may be operating out of Louisville. He told FOX19 NOW of a suspect who was busted in Columbus said the practice brought in more than $120,000 a month.
"They come in with, usually, a couple of U-Haul trucks, or something like that, and they'll block what they're doing, and they'll come in and just hit the thing, throw the skimmer in - it takes about three minutes - drive about two blocks away, and sit there and take down numbers for a couple of hours," Rhodes said.
From there, Rhodes said, the criminals usually end up buying gift cards with the stolen cash.
"There's no way for a consumer to really tell one of these things is on the gas pump," Rhodes told FOX19 NOW. "The best way to protect yourself is to either pay inside or use cash."
