Police in Nassau County say 36-year-old Neri Garcia-Ramos was running an illegal cab service when he was called to pick up the child at her aunt's home in Freeport on December 28.
He was supposed to drive her to her home in Roosevelt. Instead, authorities say he drove the child to Carroll Street, where he parked the vehicle.
Garcia-Ramos then climbed into the rear seat and exposed himself to the child, police say.
When she began to cry, he returned to the front seat and drove her home, leaving her there without collecting the fare.
An investigation by Nassau County Special Victim's Squad led to the arrest Thursday afternoon.
Detectives request anyone who may have been a victim of the defendant to contact Nassau County Crimes Stoppers at 1-800-244-TIPS.
