The Bourke Street massacre accused has declared himself “the saviour” and “not guilty” during a bizarre diatribe in his first court appearance since his arrest in January.

Dimitrious “Jimmy” Gargasoulas, 27, appeared via a video link in the Melbourne Magistrates’ Court on Wednesday on charges unrelated to the January 20 attack when he allegedly drove through the Melbourne CBD killing six people and injuring dozens of others.

Dressed in a black jumper, smiling, and seemingly in good spirits, Mr Gargasoulas tried to interject throughout the proceedings.

Despite attempts by Magistrate Kate Hawkins to gag Mr Gargasoulas and suggesting he talk to his lawyer in private afterwards, the accused persisted in a rant that reportedly shocked the court room.

“Your honour, I wanted to tell you something,” he said before lawyer Megan Casey tried to cut him off, reminding him there were media in the court.

“I just want to say that Aboriginal law is identical to Muslim law,” he went on.

“All law is illegal according to the Bible and the Koran,” he went on.

“Your honour, did you know Muslim faith is the correct faith?

“And that I’m not guilty? I am the saviour.”

Ms Hawkins then cut the video-link connection and adjourned the matter until May 26. 

Mr Gargasoulas is facing six charges of murder, 29 counts of attempted murder and conduct endangering life over the Bourke Street incident.

He is next due to appear before the court over that matter on August 1, when prosecutors are expected to give the court an update on their case.

Wednesday marked Mr Gargasoulas’s first court appearance since he allegedly killed those six people by driving a Holden Commodore deliberately at pedestrians about 1.30pm on January 20.

The victims included a three-month-old boy and a 10-year-old girl, while dozens more people were injured in the incident.

Mr Gargasoulas has been in custody since his arrest in January, but had not appeared before a court until Wednesday on the unrelated charges.

Those charges included speeding on the wrong side of the road and ignoring a police direction to stop after an incident  incident in St Kilda last year.
