The parents of a 15-month-old Greymouth boy who died in Auckland's Starship Hospital last month have been spoken to by police.
Leith Allen Hutchison was taken to Grey Base Hospital on April 21 as he was not breathing and suffering a cardiac arrest.
He was resuscitated and immediately flown to Starship, where he died two days later.
At the time of Leith's death, Detective Senior Sergeant Dan Keno said police were considering all options, including the possibility that Leith may have been assaulted in some way.
Today, Mr Keno said inquiries were continuing and they had spoken to a number of people to try to establish the events that led to the Leith's death.
