The hero father who rescued a seven-year-old girl from the dance hall rapist has described the terrifying moment his neck was slit with a scalpel and wished his attacker "pain, darkness and misery" in jail.
Nick Gilio, who went to the girl's aid after Anthony Paul Sampieri locked her in the dance studio toilet in November 2018, described the pain, horror and his lifetime physical and mental injuries since Sampieri slit his neck with a scalpel.
Sampieri, 55, committed the terrifying attack in the southern Sydney suburb of Kogarah on an evening in November 2018.
He is being sentenced in Australia today.
"I was stabbed in the abdomen," he told a hushed District Court hearing during a dramatic victim's impact statement as Sampieri sat in the dock with his head bowed and eyes cast down.
"The terror and feeling of a scalpel being dragged across the back of my neck with no thought for who I am ... or my family."
Mr Gilio said he had ongoing physical and psychological trauma, including tightness in the back of his neck and debilitating flashbacks of the attack he would have "for a lifetime".
He said the trauma and injury meant he had a lack of concentration, meaning he couldn't pursue his chosen job as a diesel mechanic.
He seemed alert but looked like he had lost weight in the months he has been in custody.
Sampieri stood with his head bowed as he formally pleaded guilty to seven charges relating to 94 offensive, menacing or harassing phone calls he made to women between August and November 2018.
After locking the girl, who was attending a class, in the toilet of the St George Dance Centre, Sampieri filmed himself committing an act of indecency on her.
Sampieri appeared in the NSW District Court at Darlinghurst in Sydney today before Judge Conlon.
In June this year, Sampieri pleaded guilty to 10 charges arising from the Kogarah dance hall attack.
Sampieri was on parole at the time of the offences on the evening of November 15, 2018.
