A man has died from "unexplained injuries" after he was taken to Nelson Hospital early yesterday morning with a severe leg wound.
Police has released his name as Richard Stephen Woolmore, 36, and is seeking information on what happened to him.
"We're treating it as unexplained as opposed to suspicious at the moment," said a police spokesman from the Nelson District Command Centre.
Mr Woolmore had suffered severe blood loss and was initially listed as being in a critical condition.
This was upgraded to "serious" by mid-morning but he later died, police said.
Mr Woolmore was taken to hospital after someone called an ambulance just before 4am yesterday.
