An "entitled" jealous ex-boyfriend who broke into his former partner's Perth home and viciously attacked and intimidated her and her male friend has been sentenced to more than four years in jail.
Mitchell Casper Marsden, 29, entered the woman's home through a bathroom window in June 2021 before finding her and her friend asleep in bed.
He then set upon the friend as the woman cowered under the bed covers, before forcing the man, who was wearing only a shirt, to leave the property.
Marsden recorded part of his attack on his mobile phone, with the footage, which was played to the District Court, showing the man covered in blood begging not to be attacked again as Marsden yelled at him to get out of the house.
The footage then showed Marsden ripping the covers off his former partner and yelling at her to look at the camera.
The court was told he then attacked the woman, including squeezing her face, head butting her, spitting on her and threatening her with a knife.
He also smashed her phone and told her he was going to send images of her to her father's social media account.
When the woman did eventually manage to flee to her car, Marsden used his elbow to smash the window.
At that point police arrived after being called by neighbours who had heard the disturbance, but Marsden continued to intimidate the woman by suggesting to her she did not want to press charges.
'Designed to intimidate and control'
Judge David MacLean told Marsden his offences were very serious because he had gone to the woman's home to intimidate her.
He said text messages in the days before the crimes had made it clear the relationship was over, and Marsden had not been justified in any way to go to the woman's home.
"It was entitled offending designed to intimidate and control the victim … [it was] your own entitled need to intimidate and punish your former partner," he told the 29-year-old.
Judge MacLean said Marsden had also "belittled, embarrassed and demeaned" the male friend who he said appeared terrified.
Marsden exposed to domestic violence
Marsden's lawyer, Paul Holmes, said his client's actions were largely a result of what he had seen when he was growing up, because he had been exposed to a lot domestic violence.
Mr Holmes insisted that Marsden was now remorseful and understood the impact his crimes had on the victims.
In sentencing, Judge MacLean took into account Marsden's guilty pleas to the three charges against him and his traumatic upbringing, but he said the offences were so serious only an immediate jail was appropriate.
He said the woman should have been able to feel safe in her own home, and a message had to be sent to the community that such conduct would not be tolerated.
Marsden was sentenced to four years and four months in jail — he will have to serve two years and four months before he can be released on parole.
