Boubacar Bathily, of Manhattan, was arrested Sunday after he turned himself in to police. He was charged with leaving the scene of a fatal accident, a felony, and driving without a license and failure to exercise care, the NYPD said.

Police said Bathily was traveling southbound on Eighth Avenue when he struck Johnson and kept going.

Several published news reports said Bathily was driving a Lincoln Town car with a livery license that he had borrowed from a friend, who was a registered driver, to make some extra money. The reports said Johnson was traveling in a silver Audi when she either jumped out or was pushed out of the car into traffic following an argument with someone inside.

Police didn't provide additional details and said the investigation was ongoing.
