Police in Readington Township, New Jersey are issuing a warning about someone possibly posing as a cop and pulling drivers over in an unmarked vehicle. An alleged victim told NBC New York that a car tailed her last week down road using a P.A. system demanding she pull over. The car had no flashing lights or any clear markings. Because of this the alleged victim had her suspicions and kept going for nearly a mile to a well lit area, before the car peeled away.
