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

Earlier, a family member told Daily Mail 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. 

The relative said the mother-of-two came out to her driveway after the girls allegedly showed up at the property. 

‘(Ms McBride) then ran out and they (allegedly) stabbed her on the driveway,’ the relative said.

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

Ms McBride is understood to have not the target of the alleged attack. 

She underwent emergency surgery last week and required a colostomy bag after her bowel and spleen were also damaged in the attack.
