An American immigrant who pleaded guilty to sexually assaulting a former girlfriend during a frenzied attack will not be deported because he was sentenced to less than a year in jail.

MacKenzie Agnant recently received a 60-day jail sentenced in the Melbourne Magistrates' Court for biting a woman on the arm repeatedly early last year and assaulting her while she showered, according to the Herald Sun.

The 42-year-old also received an 18-month long corrections order, but was released on bail after he appealed the ruling – which did not meet the one year prison sentence required for a mandatory deportation.

The father of two accused the woman of cheating on him and became infatuated with her after their short relationship ended, the court heard.

After accepting a ride home from Agnant one day, the 42-year-old repeatedly assaulted the woman as she showered.

Neighbours reported hearing the woman scream 'no' and told police officers her shrieks for help sounded like 'pure fear,' according to the Herald Sun.

The woman pushed Agnant through the shower screen before he locked her in the bathroom. She was later freed by police.

In another incident, the 42-year-old bit the woman on her arm – which Agnant claimed was a consensual act.

The American's defence barrister Marcus Dempsey argued that Agnant was drunk at the time.

'There are other ways of punishing this man other than removing him from the community,' Mr Dempsey said, according to the Herald Sun.

'His children live here and he has sought a life here. A term of imprisonment of more than 12 months would see him returned to the USA.'
