A woman has been charged over the kidnapping, drugging and assault of a teenage girl in Sydney's west earlier this year.
In July detectives from the State Crime Command's Child Abuse and Sex Crimes Squad established Strike Force Tumbridge to investigate reports a 14-year-old girl had been detained, assaulted and supplied drugs by a man and woman known to her.
Detectives arrested a 24-year-old woman at Berkshire Park on Sunday and charged her with kidnapping, drug supply, stealing, intimidation and damaging property with fire with the intent to injure.
Police will allege in court that the woman drove the girl to a hotel in Parramatta, where she was supplied methylamphetamine (ice) and gamma hydroxybutyrate (GHB).
It will also be alleged the girl was then taken to a unit in Greenacre where she was sexually and physically assaulted.
The woman appeared at Parramatta Bail Court on Sunday and was formally refused bail to reappear at Bankstown Local Court on Tuesday.
Police say further arrests are expected.
