A 30-year-old man has been charged with two counts of murder following the death of two people in Wattle Downs last week.

Emergency services were called to a Gambare Place address at about 1.45pm following a report of a person armed with a handgun at the property and a woman injured.

Upon Police arrival two people were located deceased.

Detective Inspector Tofilau Faamanuia Va’aelua, Counties Manukau CIB, says Police had been speaking with a man who was in custody for an unrelated offence, and this morning charged him with two counts of murder.
