Three dead after violent incident at Sydney home
Three people have died after a violent incident at a home in Sydney's south-west, with police arresting a 32-year-old man at the scene.
Officers were called to Juliet Close in Rosemeadow just after 1:30am on Sunday.
Police said they found the bodies of a woman in her 60s and a man in his 20s at the property.
A 64-year-old man was also found with critical head injuries and later died at Liverpool Hospital.
The arrested man was taken to Campbelltown police station for questioning.
Police have set up a crime scene and the homicide squad is assisting with the investigation.
Authorities believe the incident may be domestic violence-related, although the direct relationship between the people involved has not been confirmed.
That makes the case significant both for the immediate criminal investigation and for the wider response to domestic violence-related harm.
The incident has drawn a rapid police response in Sydney's south-west, with emergency services and investigators focusing on the home in Rosemeadow.
The deaths of three people in one incident make it one of the most serious violent events reported in the area this year.
Police said the victims were assaulted by a man known to them, according to the information released so far.
A report is being prepared for the coroner.
