In what could qualify as the worst horror a parent can mete out to a child, an Australian man has confessed to repeatedly raping his daughter for years and also inviting strangers to rape her for his pleasure.
The man admitted committing 61 offences between 2013 and 2015.
The girl, who lived with her father after her parents separated, was aged between 11 and 13 at the time.
The 42-year-old father also arranged for six other men, whom he met online, to have sex with her while he watched or participated.
The West Australian District Court in Perth heard that after his arrest he told police that while he had regrets about what he had done, "it was fun while it lasted".
On one occasion when the father and another man were filming an attack, the girl was shown shackled to a bed, wearing a dog collar with the word 'bitch' on it, the West Australian newspaper reported.
In the footage, the girl could be seen struggling against the restraints and pleading "stop, please Dad", it said.
Prosecutor Justin Whalley described the case as one of the worst of its kind to come before the courts in Western Australia.
The paedophile ring was smashed last year after a tip-off from the public.
Sentencing the father to 22 and half years in prison on Thursday, Judge Philip Eaton said the abuse would likely have "lasting and irreparable consequences" for the girl.
"You completely disregarded her welfare," he said.
"I have no doubt that you derived perverse sexual enjoyment while doing so."
One of the other men involved, a church pastor, was sentenced to 10 years in prison last November.
Two other men have also been jailed with three more still before the courts.
