Wellington Police are pleading for public help, as a family in Linden comes to terms with a mysterious death.

Bruce Coker died in Wellington Hospital early on Tuesday, after being found on the street last Saturday night.

Detective Senior Sergeant Grant Ferguson says his family are preparing to bury a loved one at Christmas, and are desperate for answers.

He says someone has vital information about what happened, and he's urging them to come forward.

Police want to hear from anyone who was in Rossiter Street between 6pm and midnight on December 20.

Anyone with information can also contact Crimestoppers anonymously.
