NSW Police said officers found the 58-year-old father with multiple stab wounds to his upper body.

He was treated by NSW Ambulance paramedics but died at the scene.

A 30-year-old man, who was later identified as the victim’s son, was arrested at the scene and taken to Penrith police station.

He has been charged with one count of domestic violence murder, police said this morning.

He was refused bail and will appear in court today.

Police said there was a history of domestic violence allegations, however, there were no reports in the past few years.

Residents told 9News that the family have been living at the home for more than 40 years.

“[It is] a quiet street, you would never think something like this would occur here,” a resident said.

“There were no indications that something like this would occur up there.”

“I can’t say I would have expected something like this.”
