Difficulty: Moderately Easy
Step1
Determine the jurisdiction in which the crime occurred. Generally, because Internet-related crimes tend to cross at least state borders, crimes are considered federal. However, some may have occurred at the state level.
Step2
Contact your local police office to report crimes that occurred within the state you are located in. Most police offices maintain a phone number for reporting crimes, which will be listed online and in the phone book.
Step3
Report crimes to the local branch of the FBI, if any part of the crime took place outside of your state. The FBI maintains offices in each state and in most large cities.
Step4
Inform the US Secret Service directly if the crime in question is hacking or Internet fraud (see Resources below). The Secret Service maintains a task force focused on computer crime.
Step5
File a complaint with the US Post Office if any part of the crime was perpetrated via the mail. For instance, if you were asked to mail a check to a fraudulent agent, you should contact the Post Office.
Step6
Report Internet fraud, spam or computer intrusion to the Internet Crime Complaint Center (IC3), operated jointly by the FBI and the National White Collar Crime Center (see Resources below). IC3 accepts online complaints and passes them along to the appropriate agency. If you already know which agency has jurisdiction, you may get a quicker response if you contact them directly.
