Pennsylvania State Police officials are investigating after, they said, a driver claimed they had been tailgated by a man pretending to be a police officer — who attempted to pull them over — while driving along U.S. 1. According to police, the driver told law enforcement officials that, on Friday at about 6:30 a.m., as they were headed northbound on U.S. 1, through Upper Oxford Township, their car was tailgated by a black Cadillac Escalade for ‘several miles” before the man behind the wheel of the Cadillac produced a red and blue “bubble light” and a siren. At that point, police said the man in the Cadillac attempted to stop the victim’s vehicle. Police described the suspected imposter in the Cadillac as “heavy-set man” who stood about six-foot, two-inches tall and appeared to be somewhere between 40 and 50 years old. He had black hair, a tan complexion and was wearing a “police style” uniform, according to law enforcement officials. State Police officials are asking anyone who may have information about this case to contact Troop J, Avondale Station at 610-268-2022.
