Family of a Gisborne man who died in Hawke's Bay Prison staged a protest yesterday over what they say is a lack of answers about how he died.
Remand prisoner Colby Heta, 33, died on the night of March 17, and the matter is currently being investigated by police on behalf of a Coroner.
Police are understood to have been viewing CCTV surveillance images, and officers had been at the prison near Hastings at least as recently as Thursday continuing inquiries.
Sources say the inmate died sometime after having been restrained by officers, but police say that a post mortem has attributed the death to a "medical event", although inquiries are continuing to establish what may have caused that event.
A small number of family arrived at the prison gates with placards about 10am yesterday, one member saying: "The justice system failed to protect him. We want answers."
Family spokesperson Yvonne Bishop, whose daughter-in-law is Colby Heta's sister, said marks on his body included those from handcuffs.
