Hero Warrawong mum's life-changing injuries after she was 'stabbed repeatedly while trying to break up teenage girl gang fight' - as girls aged 13, 14 and 15 are charged

EXCLUSIVE

A heroic mother-of-two who tried to break up a brawl between teenage girls has lost a kidney and is in an induced coma after she was allegedly stabbed multiple times.

Kristie McBride, 39, was stabbed in the head and torso outside a home on Wiget Way, in Warrawong, in the NSW Illawarra region south of Sydney, on Wednesday at about 6.30pm.

Four teenage girls aged 13, 14 and two 15-year-olds have now been arrested and charged over the alleged attack.

Daily Mail Australia understands a gang of up to five teenage girls - including one 12-year-old - allegedly arrived armed with knives and threatened to stab one of Ms McBride's young relatives.

A family member said the attack was triggered by an alleged cyber bullying incident.

The group of girls allegedly threatened to attack another teenage girl who lived at the Warrawong home.

'They all had knives and said they were going to stab her in the throat,' a relative said.

'(Ms McBride) then ran out and they (allegedly) stabbed her on the driveway.

'They were here for five seconds and they (allegedly) stabbed her and ran down the road.'

Relatives had gathered at the house after the allegedly threatening messages were sent.

It's understood Ms McBride was not the target of the alleged attack.

She has undergone surgery and now temporarily requires a colostomy bag after her bowel and spleen were also damaged in the attack.

The mother is in an induced coma and is expected to remain in hospital for several weeks.

The girls accused of being involved in the attack had allegedly warned their intended target they were coming.

'We don't know them,' a relative said 'It was after fighting back and forth on the internet and they said, ''We're coming to fight you, no weapons, no cops''.'

The family member said they believed the group had brought knives to be 'intimidating' but only one of the girl gang - who travelled from Sydney - is alleged to have inflicted any injuries.

'Me and my mum chased the girls up the street to the highway,' the relative said.

'We're okay hearing she's stable but we're all just inside the house devastated.'

Blood-stained garments could be seen strewn across the driveway after towels and items of clothing were used to try and stop Ms McBride's bleeding.

Ms McBride remains in hospital in a critical condition, police said on Thursday. 

Neighbouring houses on Wiget Way were seen with boarded up windows and doors in an area where several homes are understood to be housing commission properties.

Children's toys were also seen out the front of neighbouring houses, while a few had Christmas decorations up.

One resident said violence had become such a standard feature in the area, she no longer wanted to bring her kids to the suburb.

Police confirmed they had charged four teenagers in connection with the attack.

'Earlier today, three female teenagers – aged 13, 14, and 15 – were arrested and charged, they remain before the courts,' said a NSW Police spokesman.

'Following additional inquiries, officers attended a home in Narellan Vale and executed a search warrant at 8.45am on Thursday where they arrested a 15-year-old girl.

'She was taken to Narellan Police Station and charged with wound person with intent to cause grievous bodily harm and affray.

'She was refused bail to appear at a children's court today'.
