A man has faced court accused of stabbing his father to death in an alleged domestic violence incident in a horror start to the Easter long weekend.

Emergency services were called to Emu Plains, in Sydney‘s west about 6.45pm on Thursday following reports of a stabbing.

Police arrived at a Clouta Place address to find John Clark, 58, with multiple stab wounds to his upper body.

He was treated at the scene but could not be revived.

His son, Evan Davis Clark, 30, was arrested at the home and taken to Penrith Police Station, where he was charged with murder (domestic violence).

Clark was unaware that his father had died when he faced court on Friday afternoon.

‘Is he dead?’ he asked.

‘Yes, Mr Clark, he is,’ the magistrate replied.

The Emu Plains incident sparked a major emergency response

Clark told the court that he ‘just wants to do my time’ and thanked the magistrate in Russian at the end of the hearing.

Clark did not apply for bail, which was formally refused.

Police will allege that the pair had been heavily drinking and play-fighting together before Clark stabbed his father.

Detective Acting Superintendent Michael Cantrell told reporters on Friday that a number of witnesses had been spoken to, but would not confirm if anybody else was home at the time.

He confirmed that both Clark and his father had a history of domestic violence.

‘However, there have been no interactions with police for a number of years around domestic violence,’ Det Act Supt Cantrell said.

‘The Easter long weekend is supposed to be a time for families to come together, and for someone’s family to start off a long weekend in such tragic circumstances is very tough.’

Footage from the scene on Thursday night showed more than a dozen emergency vehicles blocking off the usually quiet cul-de-sac.

Detectives removed bags of evidence from the scene on Friday

Residents more than 5km away reported hearing sirens as a police helicopter hovered over the scene.

Detectives and forensic officers returned to the home on Friday, where they were seen taking away bags of evidence.

‘Very confronting scene for police who did an amazing job to arrest the (alleged) offender in the location. It was very good police work,’ Det Act Supt Cantrell said.

It’s understood the family have lived at the home for more than 40 years and were among the first to move into the street.

‘[It is] a quiet street, you would never think something like this would occur here,’ a shocked neighbour told Nine News.

‘There were no indications that something like this would occur up there.’

Police investigations continue under Strike Force Hawklar.

Clark will reappear in Penrith Local Court on May 29.
