Richard Pusey pleaded guilty to a host of charges including unlawful assault, using a carriage service to menace, theft and criminal damage in the Melbourne Magistrates Court on Monday.

The 43-year-old has served his 10-month jail term for outraging public decency and other offences in relation to the fatal crash but remains in custody on the separate charges.

The former mortgage broker admitted to unlawful assault and using a carriage service to menace where he dragged a woman up the stairwell of his Fitzroy home on December 27 last year.

When the pair reached a landing Pusey put a noose around his own neck for 10 seconds, the court was told.

Police broke down the door and told the disgraced mortgage broker to surrender but instead he went out onto a third floor balcony and climbed onto the roof.

About 2.30am the following morning officers were able to convince him to come down from the roof and was taken to St Vincent’s hospital for a mental health assessment before he went to the police station.

“There was a change of medication five days before the incident in December,” Pusey said during the hearing on Monday.

Hours before he unlawfully assaulted the woman Pusey sent text messages to a sergeant’s mobile phone on December 26 which included one that read: “I’ll kill everyone then. Thank you for nothing”.

He also abused an officer during a three minute and 30 second phone call telling him: “Come and save the f***ing world you c***” and “why don’t you get cut in half you f***ing animal”, a police summary read.

Pusey also pleaded guilty to a range of charges including scratching a gas tank of a motorcycle at Richmond in March 2019 and stealing keys from another driver in a parking dispute in Melbourne’s CBD in October 2018.

As well, he admitted to harassing a Westpac bank employee which included shocking emails which “terrified” the worker and their family, the court was told.

He sent a series of emails to the victim and another Westpac employee on August 27 from 12am.

“How’s about you post me your letter to MY fuxking postal address you f***wit c***. Where do you live, you half with lying c***. Your wife’s worth a root is she? Tell me about her,” one message read.

Another sent about 9.36am referred to the victim’s daughter saying “today’s a great day” because the child would turn two and “she’s going to save the world because she can use an iPad”.

Pusey also admitted to criminal damage for dropping a slab of Coopers Pale Ale on the ground at a BWS in December 2020 after a security guard said he would not be served because he was banned.

His lawyer Carmen Randazzo said her client should be sentenced to time served, which was 118 days on remand.

She said the unlawful assault charge was on the “lower end” of seriousness and the maximum penalty was three months.

But prosecutor Meaghan McDonnell said time served and a community corrections order would be appropriate to ensure protection of the community.

“Some of the offending the accused has pleaded guilty to today is of the nature of being provocative and on occasions being antagonistic,” Ms McDonnell told the court.

The order would formalise and ensure he undertook mental health treatment, she said.

Pusey came to national attention after he was charged with outraging public decency following the Eastern Freeway crash in April 2020 where four officers were killed.

Ice-addled truckie Mohinder Singh ploughed into the officers while Pusey escaped unharmed because he was urinating away from the road. Singh was jailed for 22 years after pleading guilty to four counts of culpable driving causing death.

Lynette Taylor, Glen Humphris, Kevin King and Joshua Prestney died in the horror crash.

Magistrate Hayley Bate will sentence Pusey on the latest charges on Wednesday morning.
