Officers were called to an Arnos Way property about 4.45pm, where they discovered the body of a 42-year-old man.
The street remained a police scene on Saturday as forensic officers scoured the home for clues not far from Hudson Park Primary School, which is on the same street. Major Crime Squad detectives want to speak with anyone who witnessed suspicious activity in the area in recent days.
They are particularly interested in information on anyone who had reason to visit the property. Call Crime Stoppers on 1800 333 000.
