Police say the Levittown resident was carrying handcuffs and wearing a shirt with police patches. They say Mackrodt displayed a weapon - later found to be a BB gun.
The 39-year-old Farmingdale woman was reportedly driven around the Levittown area and finally delivered unharmed to the Yellow Cab Company. There, the suspect again identified himself as a policeman and instructed the dispatcher to give her a ride home.
Police say the dispatcher noted Mackrodt's vehicle and plate number and notified authorities. Mackrodt was pulled over on Ridge Lane and placed under arrest. A fake police-type shield, laptop computer and BB gun were recovered.
