'Sick' Rapist Who Brutally Attacked Young Girl In Dance Hall Toilet Blames Ice Addiction

Convicted rapist Anthony Sampieri has referred to the "insanity" of drug addiction as he apologised for his sex crimes, including violently attacking a girl in the toilets of a Sydney dance studio.

An apology was directed to the then-seven-year-old girl Sampieri punched, bound and raped in the Kogarah toilets in November 2018.

"I am so so sorry I did what I did " Sampieri testified at his sentence hearing in the NSW District Court on Friday.

"Using crystal meth I believe that led me to what I did. I am sorry I let you down by using crystal meth again."

He also apologised to diesel mechanic Nick Gilio who stopped the attack when he confronted the knife-wielding Sampieri.

Sampieri further apologised to a number of women to whom he made offensive telephone calls.

"I would like to apologise for the sick behaviour," he said.

The 56-year-old knew well from his past crimes of the link between his use of the drug ice and sexual promiscuity - such as masturbating in toilets.

Despite knowing that using ice increased the risk, he continued to use the drug, explaining it was "because it will be different this time".

"That is the thinking that goes with the addiction - it will be different this time," he said.

Sampieri has pleaded guilty to 10 charges related to the attack on the girl including three counts of sexual intercourse with a child under 10.

He pleaded guilty to seven charges related to sexually explicit and harassing phone calls he made to women in the months before the dance studio attack.

His sentence hearing continues before Acting Judge Paul Conlon.
