COLLIER COUNTY, Fla.- "I'm calling you from the Department of Federal Crime Law Enforcement Division."

The man in this voicemail identifies himself as Officer Sean, he even gives a bad number. The Collier County Sheriff's Office said this crook has gone after several people in Naples.

"Saying they were contacted by people who had said they had missed court or they had an unpaid fine," said Lt. Chad Parker with the Collier County Sheriff's Office.

And if they didn't call Officer Sean back, "We will step over with the legal procedures. You will be in a big legal mess."

Even threatening to arrest them.

"Call us back before something goes wrong with you."

Lieutenant Chad Parker with the Financial Crimes Unit of the Sheriff's Office said scammers will ask for a credit card number over the phone. In Parker's career it's the first time he's actually heard one of these calls. He also said it's not hard to commit a scam like this, you can easily change your number, even your voice, using different websites online.

"And if you listen to it, it sounds so ridiculous, but unfortunately people fall for it," said Lt. Parker.

And if the bad guys succeed, it opens the door to all kinds of fraud.

"Credit card fraud, or identity theft, or charges on your credit card that are usually for online shopping."

Luckily, the people who were targeted last week did not fall for that scam and alerted investigators. Bottom line, no legitimate law enforcement agency will call you threatening to arrest you if you don't pay a fine.
