A Springfield Township man charged this week with impersonating a police officer found himself in more legal trouble Thursday.

Sean P. Duffy, 48, was arrested Monday after Summit County sheriff’s deputies said they found him in a car decked out like a police cruiser. The arrest came after a nearly monthlong investigation.

Sheriff’s Inspector Bill Holland said the investigation began March 11, when an automobile repair shop reported that a customer came in and asked a mechanic to install police lights on his vehicle.

“The vehicle was a white Ford Crown Victoria Police Interceptor with ‘K9’ stickers on the rear and both sides of the vehicle,” Holland said in a news release.

The mechanic told investigators the car had a bag labeled “POLICE” inside along with handcuffs and a police baton.

The customer, who authorities say has been identified as Duffy, wore a vest that read “POLICE,” and he had a badge on his belt.

On Thursday, Springfield Township police issued an arrest warrant for Duffy on a misdemeanor charge of telephone harassment in connection with the auto repair shop that worked on his Crown Victoria.

Duffy, who allegedly made the harassing call Wednesday, did not immediately respond to several Beacon Journal telephone messages seeking comment on the impersonation charges and Thursday’s warrant.

Another report in the monthlong investigation, according to Holland, came to light March 15, when a Crown Victoria The car had emergency flashing lights, a siren, a dash camera and what appeared to be police radios.

Holland said customers were concerned because the vehicle had expired plates, and it appeared the driver might have been impersonating a police officer.

He said deputies investigating Duffy, who was driving around in the fake police cruiser, have found that he has no police training and has never been employed as a law enforcement officer in Ohio.

Duffy, who is also known as John Kidd, had been pulled over at least four times in the past week.

Holland said Duffy told the officers who pulled him over that he was a retired sheriff’s deputy, and on another occasion claimed to be a retired Canton police officer.

Authorities are asking the public to call the Summit County Sheriff’s Office at 330-643-2147 if they have any information about Duffy or suspect that they might have been pulled over or interacted with someone pretending to be a police officer.
