Police have charged a Gisborne woman with manslaughter in relation to the death of a seven-week-old baby boy who died in Gisborne Hospital in December last year.
The woman is in her late teens.
"The charge follows a lengthy inquiry that was started soon after we were alerted about the child's injuries by hospital staff," said Detective Senior Sergeant Craig Scott.
"It's alleged the baby died from non-accidental injuries, sustained prior to his being admitted to hospital."
Detective Senior Sergeant Scott said it was the type of inquiry where extra care was essential.
