THE man accused of murdering Indian bus driver Manmeet Alisher on Friday by dousing him in flammable liquid, has been confirmed as a former mental health patient with Queensland Health.

Health Minister Cameron Dick confirmed that the man charged with killing Mr Alisher, and attempting to kill 11 others -- Anthony Mark Edward O'Donohue - had been treated by Queensland Health's mental health services in Brisbane's south.

The Metro South Hospital and Health Service will now conduct a mandatory internal review on the treatment and services O'Donohue received from Queensland Health.

That health service includes major hospitals in Beaudesert, Logan, Redland, plus the Princess Alexandra and QEII Jubilee hospitals.

Mr Dick said there would also be an "independent external investigation".

"I have requested the Director-General of Queensland Health to commission an independent investigation … regarding treatment provided to the accused."

That review will be done by Professor Paul Mullen, someone Mr Dick describes as one of the country's top forensic psychiatrists.

"It is expected that this investigation will be completed within eight weeks.

"To the extent possible, any findings and recommendations of this investigation will be released quickly."

Manmeet Alisher shared this photo on his Facebook page. The 29-year-old was killed on Friday when a passenger threw 'an item' at him that set on fire.

The revelations about the mental health of the accused murderer come as Mr Alisher's remains are taken back to India by his brother Amit.

His family and the Indian Government have also raised their concerns that the attack may have been racially motivated, although Queensland Police say there is no evidence to suggest that.


Was bus driver killed over race? Indian PM wants answers

FEARS that bus driver Manmeet Alisher may have been fatally set on fire because of his race have reached the highest posts in the land, with Indian Prime Minister Narendra Modi demanding answers from Malcolm Turnbull.

Mr Alisher was killed on Friday after a flammable liquid, thought to be similar to a molotov cocktail was allegedly tossed inside the bus. The driver died at the Moorooka stop, in full view of his passengers.

The Indian Government has confirmed Mr Modi telephoned his Australian counterpart last night.

Mr Modi delivered "a sense of concern being felt in India over the recent brutal killing of Mr Manmeet Alisher, a person of Indian origin, in Australia".

In a statement, the Minister of External Affairs wrote that Mr Turnbull "expressed shock at the killing and conveyed that the matter is being investigated".

Mr Modi also gave Diwali greetings in honour of the Hindu festival of lights, which began on Sunday

In India, however, suspicion remains after Indian students were targeted in race-related attacks in Melbourne in 2009.

Mr Alisher's borther Amit arrived in Brisbane on Sunday morning on a flight to take his brother's body home.

He told the ABC that his family understood there was no suggestion of it being a racially-motivated attack, they feared it might be the case.

"We suspect that it may be (racially motivated)," he told ABC.

"We would like to see due process, we have faith in the Australian system."

Mr Alisher's parents are yet to learn of their son's death, the news kept from them due to their age and frailty.

Long-time family friend Winnerjit Goldy told Fairfax Media said the 29-year-old was a "visionary man" who led his community.

"He was not only driver, he is a shining star, a good artist, a good hero, he had made two movies, he was a good social worker, he did a lot of things for his community in Australia even in India also," he said.

Anthony Mark Edward O'Donohue, 48, fronted Brisbane Magistrates Court on Saturday.

He is facing charges of murder, arson and 11 counts of attempted murder.

He is due to appear in court again next month.

In Mr Alisher's home village in Punjab in northern India, Diwali celebrations have been cancelled as the community mourns.

Mr Alisher was given Australian citizenship six months ago.

Mr Goldy said he was shocked such an atrocity could occur in Australia.

"A country like this one, we never expected these things, it can't be happening, but it has."
