They also give you enough information to identify yourself but they don't have all your information so therefore do not give them any.  I have the phone number and company name going to the detectives.  They continue to call and harrassing phone calls threatening to take warrants out and affidavits that they allegedly mail out but an address they don't have for you.  Don't give them your address just go directly to the police and file a police report and then get a certified police report for your records and stay in contact with the detective assigned to your case.  Be safe.
