It's alleged the man sexually assaulted her as well as seriously physically assaulting her.

The man then left the house and the woman attended the nearby Broadmeadows Police Station shortly afterwards to report the matter.

The victim was then taken to hospital for treatment.

The man, of no fixed place of address, was arrested shortly after 3pm in Meadow Heights yesterday.

He was interviewed by police last night and charged with five counts of rape, false imprisonment, intentionally causing injury, threatening to kill and committing an indictable offence while on bail.

The man will face Melbourne Magistrates' Court today.
