An Irish nanny has been charged with "violently" assaulting a baby who later died, US authorities said.
Aisling McCarthy Brady, 34, from Quincy, Massachusetts, had been living illegally in America and is alleged to have been the sole carer for the girl on January 14 - her first birthday - when she suffered injuries "consistent with abusive head trauma", authorities said.
The baby, Rehma Sabir, died two days later in hospital after suffering brain damage.
Brady is currently being held and pleaded not guilty to assault and battery on a child causing substantial bodily injury.
However, further charges are anticipated following the conclusion of the final report by the Chief Medical Examiner, the district attorney's office said on its website.
