Abena Yeboah, 71, of the Bronx “had been hired to care for the infant,” Bergen County Prosecutor Mark Musella said.
City police were notified after a nanny cam captured her abusing the child, he said.
New York City police arrested Yeboah on a Hackensack Police Department warrant, Musella said.
She remained held pending extradition to Bergen County to face child abuse charges, he said.
