CAPE CORAL, Fla. - A Cape Coral man says he received 8 calls from a person claiming the U.S. Treasury had money in his name... but wanted personal information and a fee up front.

"They told me they were from the Treasury Department and said they had about $18,000 for me and that all I needed to do was send them some money," said the man, who didn't want to be identified.

He says the callers rang his line numerous time on Sunday, before finally hanging up when he began to ask questions.

Authorities say unclaimed money scams have been a hot choice among crooks for the past few years - especially in the weeks following the April 15th tax deadline.

"It would be fairly common at this time of the year as people are waiting for their refund checks other things are happening and consequently they'd be called and think, 'Oh boy, I'm going to get money," said Kevin Farrell with the Lee County Sheriff's Office.

Investigators say a scam giveaway is if there is a fee to file the claim. State governments do not charge money for searching their database of unclaimed accounts or for making a claim.
