A man has been arrested for perverting the course of justice in relation to the homicide investigation into the death of Jasmine Wilson.
Wilson, 30, was left at Whanganui Hospital on July 31 with what were deemed to be non-accidental injuries and died on August 2.
A homicide investigation was later begun with police looking into the circumstances that led up to her death, including by examining two different properties and a vehicle.
On Friday, police revealed that during the investigation a 48-year-old man had been arrested for perverting the course of justice. He will appear in the Whanganui District Court on Saturday.
Police are continuing to urge anyone with information about Wilson's death to come forward, even if people believe the information isn't significant.
Earlier this week, Wilson's mother, Brenda Reuben, issued an appeal for information.
"Our family is grieving and we are desperately hoping for closure," she said.
"Jasmine was a loved mother, daughter, sister and granddaughter. Her family and friends can't understand why this has happened to her.
"No one should have to see a family member in the state we saw Jasmine in. She was unrecognisable.
"There are people who know what happened to her. We are pleading with you to come forward and do the right thing."
Anyone with information is urged to call Police on 105 or anonymously call Crimestoppers on 0800 555 111.
