A 47-year-old Bedfordale man is among eight men arrested by child abuse squad detectives for allegedly using a girl as a sex slave while she was aged 11 to 13 years.
The men face 503 charges between them.
The girl’s father was amongst those charged and police alleged he facilitated access to his daughter for the men.
An investigation began in April after a tip off from the public.
Detectives alleged the girl was the victim of sexual offences and child exploitation over two years.
The other men charged were aged between 34 and 47 years and were from Attadale, Wanneroo, Wembley, Coodanup, South Bunbury and Banksia Grove.
Detectives also found 200,000 videos and four million images depicting child exploitation material from devices from one of the men charged as a result of operation ripstop.
The 148 charges against the father included knowingly sexually penetrating a child known to be a lineal relative, sexual penetration of a child under 13, aggravated indecent recording of a child under 13, indecent dealing of a child under 13, stupefying with intent to commit indictable offence and distributing child exploitation material.
The other men were charged with various offences including sexually penetrating a child under 13 and indecent dealing.
The Bedfordale man was charged with 13 counts of indecent recording of a child under 13 years and two counts of indecent dealing with a child under 13 years.
Detective Superintendent Glenn Feeney said the girl had been rescued from the situation.
“She was rescued from this horrible situation she was in,” he said.
“She is safe, she is receiving the care that she requires and that will be an ongoing situation.”
A police spokeswoman said it should be remembered every image, photograph or movie like the material found in this investigation represented a child being abused.
“Luckily in this case the child was identified and arrests made,” she said.
