We only investigate the cases that are related to the actual passing of the forged or counterfeit checks, or the fraudulent use of a credit card. If your checks are stolen from anywhere other than the mail, you should call 911 to make your police report. The offense will be forwarded to the police substation that handles theft offenses in your area. A Detective assigned to that division will be assigned to work the offense. Our office does not investigate the theft of checks or credit cards.
