A man will reappear in court next year after allegedly holding his former partner against her will for three days.
It is alleged that, between November 10 and 13, a 28-year-old woman was held against her will at an address in St Marys.
The woman has told police that during this time she was sexually assaulted on a number of occasions.
After three days the woman was allowed to leave and she reported the matter to police. It is alleged the matter is domestically motivated.
She was later admitted to hospital for treatment of her injuries. The 28-year-old woman has since been discharged.
As a result of inquiries by detectives attached to St Marys Local Area Command, a 32-year-old man was arrested.
He was charged with assault occasioning actual bodily harm, detain for advantage and sexual assault.
The St Marys man appeared at Blacktown Local Court where he was again refused bail prior to his reappearance at Penrith Local Court on January 30.
