Another murder charge and 28 attempted murder charges have been laid against Dimitrious Gargasoulas, the man accused of Melbourne’s deadly Bourke Street rampage in January.

Six people died and more than 30 were injured when pedestrians were struck by a car driven through the pedestrian mall during the busy lunch period.

Gargasoulas, 26, of Windsor, was charged with five counts of murder after being arrested.

Another murder charge has now been added over the death of Bhavita Patel.

Ms Patel, from Blackburn South, was a director at global accounting firm Deloitte.

She died in hospital ten days after the incident.

Gargasoulas has also now been charged with 28 counts of attempted murder and conduct endangering life.

He had been on bail at the time of the attack, which prompted a wide-ranging review of the state’s bail system.

He has also now been charged with attempted murder, intentionally causing serious injury, robbery and unlawful imprisonment following two incidents in Windsor before the Bourke St incident.

Victoria Police said he would appear in court again on December 15.
