Karen Straughn, Maryland's assistant attorney general for consumer protection, said a resident told her at a Baltimore County public information meeting of a scam involving car thieves luring motorists into getting out of their cars with the doors unlocked by placing $100 bills under their windshield wiper blades.

"Because it's something of a frightening nature, if this happens to someone, we hope they will take the proper precautions," she told WJLA-TV. "With the fact that the holidays are coming up and more shopping, we believe this is something that could occur in this period of time." The Prince George's County Police Department and the Baltimore County Police Department said they have no record of the $100 bill scam being perpetrated in the state, but a spokesman for Baltimore County's auto theft task force said similar scams have been documented.

When everyone gets out of their cars, a thief will jump in the victim's car and drive off," the spokesman told ABC News.
