Ex-Foster Care Worker Charged Over Alleged Child Sexual Abuse

Police have charged a former foster carer over allegedly sexually assaulting a young girl several times in NSW's Newcastle region.

Officers said a 42-year-old man sexually abused a girl -- then aged nine -- on several occasions while she was in his care in 2017.

Following an extensive investigation, detectives arrested the man at a home on the Central Coast last month.

He was taken to Wyong Police Station and charged with four counts of aggravated sexual assault and committing an act of indecency with a person under 16 years of age.

The man was refused bail to appear at Wyong Local Court last month and will re-appear at Newcastle Local Court on Wednesday.
