A woman has been arrested and charged with murder in relation to the death of 17-year-old Demetrius Pairama at a property in Māngere on July 7.

The 28-year-old appeared in Manukau District Court yesterday. 

The family of the deceased say the cause of her death was unknown, but they believed the teenager struggled and that DNA was found under her fingernails. 

Police say they're yet to rule out further arrests in relation to the death as enquiries remain ongoing.
