Todd Jeffrey Blumencranz,35, was booked into the Pinellas County Jail Thursday night on the felony charge.
He is accused of pulling over a woman for speeding on her way to work on March 17 at Belcher Rd at Nursery Rd.
The woman told officers that she was pulled over by a silver car that had red and white lights on the mirror and dashboard. The man told her he was an off-duty police officer on his way to work, took her license back to his car and also pretended to communicate via an earpiece. He also had a clipboard with him.
The would-be officer told her he was going to let her off with a warning.
The woman contacted police once she got to work. She later positively identified Blumencranz from a photo as the one who pulled her over.
