DelRea Good, 52, said she was afraid to stop on an isolated road and instead drove less than a mile to stop at a Kohl’s parking lot, where Patrolman William Marshall arrested her.
Good said she acknowledged the car as a marked police vehicle, waved out the window, turned on her emergency flashers, and drove to a stop at a public area.
“I felt I didn't do anything wrong," Good said to the Times of Northwest Indiana. "I got to a safe place and I told him that."
Good also told the paper that Marshall bruised her during the arrest and “bullied” her at the station by claiming that Advil and other medications in her possession were controlled substances.
Porter County Sheriff's spokesman Sgt. Larry LaFlower said Good violated state law requiring motorists to yield to emergency vehicles.
"The sheriff's office supports our officer's decision in this matter," LaFlower said.
However, Reason.com cites several cases of officer impersonations including some involving sexual assault. In 2012, Indiana State Troopers warned motorists of bogus troopers on Interstate 80.
