The post-mortem examination of a man who died in police custody on Sunday has been completed, however it will be two weeks until a toxicology report determines his cause of death.
The 20-year-old was taken to the Manukau Police station in the early hours of Sunday morning and was pronounced dead about 6.10am.
A post-mortem examination was undertaken yesterday afternoon but the cause of death was still unknown and would be be a matter for the coroner.
The man was previously known to police and would was due to be named tomorrow, Counties Manukau police spokeswoman Kimberley Mathews said.
Counties Manukau police district commander Superintendent John Tims yesterday said the man's death followed a police callout to an address where his family were found trying to restrain him.
