Police Probe Alleged Intruder's Death After Struggle With Father Inside Home

Police are investigating the cause of death of an alleged intruder following a confrontation with an occupant inside a Sydney home.

Officers questioned father Francois Schwartz, 44,  after a 35-year-old man who allegedly entered his Harrington Park home was found dead on Sunday.

Neighbours said they saw a man running barefoot down the street around the time of the incident.

"The thing I noticed the most was that he was barefoot," Dominic Lombardo told 10 News First.

"It was strange. He was heavily breathing and it was like he was mumbling to himself."

Police said Schwartz awoke to the sound of his dogs barking about 7.30am and found a man in the loungeroom of his Westwood Court home.

After "challenging" the alleged intruder, the pair got into a physical confrontation, during which the intruder fell unconscious.

Two members of the public commenced CPR before emergency services arrived, but paramedics were unable to revive the man and he died at the scene.

Schwartz was taken into custody for questioning and was released without charge on Sunday night pending further police inquiries.

Police are investigating the man's cause of death including the level of force used by Schwartz.

"People are entitled to their home, and they're entitled to use reasonable force to protect themselves and their property," Chief Inspector Shane Woolbank said.

Police asked for help identifying the deceased man described as having "a ginger-like moustache and beard, wearing a blue sleeveless top and grey Nike training shorts".

He also had two distinctive tattoos -- one on the left upper inside of his arm and the second on his left upper chest -- as well as a scar on his left upper shoulder.

Anyone with information about the incident is being urged to contact Crime Stoppers on 1800 333 000.
