Officers have spoken to Mr Kapluggin's family and expressed our condolences for their loss," said District Crime Manager, Detective Inspector Karl Thornton. "The family have expressed their gratitude to our staff for being able to hold someone to account and have requested their privacy be respected."
Emergency services were called to the Achilles Ave home about 1am on February 3 where they found Kapluggin dead.
Police launched a homicide investigation and cordoned off the modest green and white home opposite the popular Williamson Golf Course to undertake a scene examination.
At the time police said the occupant of the house was helping with inquiries, but would not comment on the relationship between the occupant and Kapluggin.
Ballantyne is currently one of the registered owners of the property and had the Achilles Ave address as his registered address on court documents.
Little is known about Kapluggin, who is believed to have family representatives in New Zealand.
