The Criminal Complaint Unit assists the public in filing criminal complaints, both in person and in writing.

Please read this information on what steps to take if you believe that you have been a victim of identity or credit card theft.
Identity - Credit Card Theft
Be wary of unsolicited requests for your personal information. Legitimate financial institutions will not call an individual to verify personal information that is already on file.
Real Estate Fraud
Never sign a deed to save your house from foreclosure. Before signing any documents, consult with an attorney. If you make the mistake of signing a deed over to a third party with a promise to transfer the property back; be aware that you no longer own the property and that the new owner will probably try to evict you from the property based on the transferring of the deed.
If you have won a legitimate contest or sweepstakes, you would NEVER be required to wire money as part of claming your prize.
