Multiple police departments across the United States, including Irvine and Mooresville, are warning residents about ongoing phone scams involving impersonation of law enforcement. Scammers are using manipulated caller IDs to pose as police officers, claiming that victims owe fines or have outstanding warrants. The Irvine Police Department specifically advises victims to request identification and other verification details from callers and to report suspicious calls to their office. Similarly, the Mooresville Police Department emphasizes that genuine law enforcement agencies will never solicit money or personal information over the phone. Additionally, the Asheville Police Department highlights a sophisticated scam related to jury duty, where victims are threatened with fake warrants unless they pay. Authorities urge the public to remain cautious and verify any such claims through official channels.
