We have received several reports of SCAMMERS pretending to be Lewiston Police Officers (using the names of LPD members). THIS IS A SCAM.
Claiming there's an outstanding warrant for an unpaid traffic ticket or other violation, police impostors threaten immediate arrest unless you promptly pay a supposed fine. Sometimes they demand your credit card number. The threat is typically made by phone, using readily available "spoofing" software that makes your Caller ID falsely show that the call comes from the local police department. Reality: Police neither give advance warning of arrests nor solicit money for unpaid fines. If you really owe, you'll be mailed a court summons or other official notification you can verify.
