Police launched an investigation into his death in custody on October 9.
Acting Superintendent Sunny Patel, the relieving Auckland City District Commander, said at about 10.56am on October 6 - a day after the brutal dairy attack took place - police found the man unresponsive in a cell.
Patel said police immediately administered first aid and called an ambulance.
The man was then transported to Auckland City Hospital but died on October 8, police said.
“A critical incident investigation is now under way, and the Independent Police Conduct Authority [IPCA] has been notified,” Patel said.
The Coroner has also been notified and a post-mortem examination will be completed.
As standard procedure, police have also notified WorkSafe of the incident at the Auckland Custody Unit.
A man and a woman were stabbed in the October 5 attack at the New Windsor Dairy and Lotto shop on New Windsor Rd.
Detective Inspector Glenn Baldwin said at the time members of the public helped arrest the man.
Police spent the day at the scene, cordoning off the block of shops on the corner of Maioro St and New Windsor Rd.
Dairy and Business Owners’ Group chairman Sunny Kaushal said then news of the attack was “heartbreaking”.
“We have already had deaths in our industry, and we were fearing more violence because the Government is failing to take any action. New Zealanders are sick and tired of the lawlessness.”
