Dayna Isaac, 28 was found dead inside a Colless St unit in Penrith in western Sydney, about 4.15pm on Monday
The mother of a man charged with murder after his girlfriend was found dead in a western Sydney unit has unleashed on reporters, chasing them down the street while screaming ‘f*** off!’.
Paul Sultana, 32, was arrested in dramatic scenes early Tuesday after his mother Janet Tsiliris discovered his new partner Dayna Isaac, 28, dead and partially unclothed inside her Penrith home.
Heavily armed tactical operators spent more than an hour negotiating with Sultana in the early hours of Tuesday morning, before taking him into custody.
He was charged with murder on Tuesday afternoon and refused bail to appear in Penrith Local Court on Wednesday.
It comes as Ms Issac’s shattered ex-husband and the father of her children paid tribute on Tuesday night, vowing to ‘look after our girls.’
Ms Isaac, a mother of two, had a long-term friendship with Sultana before their relationship turned romantic late last year.
It’s understood investigators allege Ms Isaac’s cause of death is physical assault.
Media gathered outside the Cranebrook home on Tuesday where Sultana was taken into custody hours earlier.
By the afternoon, forensic teams, who spent the morning scouring Ms Isaac’s apartment, began work on Sultana’s nearby home, where he lives with relatives.

Shortly after the investigators left, Ms Tsiliris and her father Basil pulled up outside the home in a red car.
But as she was approached by a Daily Mail Australia reporter, Ms Tsiliris charged across the rubbish-covered lawn and started swearing.
‘You f***ing vultures!’ Ms Tsiliris screamed.
‘F*** off! Get the f*** out of here!’
As the reporter turned to walk away, Ms Tsiliris followed her down the street.
She then returned to the house where she could be heard yelling to her father: ‘Go chase them dad!’
After Sultana allegedly killed Ms Isaac at her Penrith unit, police allege he dumped her car in bushland in the nearby suburb of Castlereagh.
Officers then tracked Sultana to his Cranebrook home and called for back up before moving in to arrest him.
Police shut down the street when the heavily armed tactical operations unit arrived.

Specially trained officers negotiated with Sultana for more than an hour before taking him into custody.
Meanwhile, Ms Issac’s ex-husband broke his silence on Tuesday night with a heartfelt tribute to the mother of his two daughters.
‘Love you forever and always. I promise I’ll look after our girls until we meet again my angel,’ Mikkel Isaac wrote.
He also posted a series of photos of the pair in happier times, including several of them kissing and dancing on their wedding day in 2017.
Ms Isaac’s shattered father Garry English also paid tribute to his ‘princess’.
‘I’m not in a good place..I’m in complete shock,’ he told The Daily Telegraph.
Ms Isaac’s best friend has set up an online fundraiser to help support the grieving family, which has already raised $4,000 within hours.
‘Our beautiful Dayna was taken way too soon,’ she wrote.
‘Dayna was a friend to everyone. She leaves behind 2 beautiful children who will miss her dearly. As you can understand this is a difficult time for her friends and family.
‘We are asking for donations to help give Dayna the send off she truly deserves and to help her family with the costs of raising her children.’

Earlier on Tuesday, police revealed officers attended Ms Issac’s home on Monday after neighbours reported hearing a blazing row,
When police knocked on a mother-of-two’s door they got no answer and heard nothing inside.
But just 90 minutes later, at 4.15pm on Monday, police were back at the Colless St unit in Penrith, in Sydney’s west, where they found Ms Isaac’s body.
Officers were accompanied by her new boyfriend Paul Sultana’s mum, who had called them, with her 32-year-old son now in police custody.
The timeline of events has been confirmed by NSW Police to Daily Mail Australia, with police first called to the unit between 2.30pm and 3pm on Monday.
A neighbour had called police to report a ‘disturbance’ coming from Ms Isaac’s home but when officers turned up at the unit, nobody answered the door and they left.
Officers found Ms Isaac’s car burned out in bushland at 3.45pm, 13km away from her home near Castlereagh.
‘I was out the back and just heard an explosion. We looked across the street and didn’t think anything of it,’ an unnamed local told Daily Mail Australia.
‘Then we saw a white car drive in there later but we didn’t realise it was police car.
‘That area is called the drop zone. They do military drills and some people ride there motorbikes in there sometimes even though they aren’t meant to.
‘We didn’t see smoke or fire or anything about 4.30pm.’
Half an hour later, Ms Isaac’s body was discovered by Sultana’s mother, who had gone to check on her.
She then drove to Penrith Police Station and reported her horror find to officers.
Sultana was arrested at about 3.25am on Tuesday, and was charged over her alleged murder 14 hours later.

Another woman who lives in the same building as Ms Isaac said she woke up this morning to the property taped off and police officers scouring the site.
‘It was quite scary, I was at work yesterday and found out over Facebook a woman had died in my street,’ she said.
‘When I came home late last night there was only one police officer there, but when I came out of the building this morning they were everywhere.’
