Police have launched a homicide investigation following the death of a baby girl in Wanganui from a non-accidental head injury.
Hinekawa Topia, aged 2 months, one of triplets, was driven to Wanganui Hospital by her parents just before 1pm on Thursday as she was not breathing.
Attempts by her father and hospital staff to resuscitate her were unsuccessful.
A post-mortem examination had revealed she suffered a head injury considered non-accidental, police said today.
Hinekawa's twin sisters were in hospital for assessment as a precaution and, along with a 5-year-old boy, had been placed in the interim custody of Child Youth and Family.
