The man who died in Selwyn has been named as Luke Riddell.
Police launched a homicide investigation after the 28-year-old was found dead in Charing Cross on October 13.
Emergency services were called to the scene, between Grange Rd and Telegraph Rd, about 3.30pm.
Detective Inspector Corrie Parnell said a number of forensic scene examinations were under way in the area and members of the public could expect to see a "significant police presence" for the next few days.
Police previously said initial inquiries suggested an altercation had taken place between two men.
