Queensland’s health minister has ordered an independent review of the mental health care given to the man accused of torching a Brisbane bus driver.

Cameron Dick has revealed Anthony O’Donohue, 48, received mental health services before Friday’s horrific attack that killed Brisbane City Council driver Manmeet Alisher.

Mr Dick did not say when Mr O’Donohue was treated but said he’d previously accessed mental health services through the Metro South Hospital and Health Service.

He has ordered an independent external investigation into the adequacy of the care provided, to be led by Professor Paul Mullen.

“It is expected that this investigation will be completed within eight weeks,” Mr Dick said in a statement on Monday.

“To the extent possible, any findings and recommendations of this investigation will be released publicly.”

Mr Dick said an external investigation was necessary given the very serious nature of the attack on Mr Alisher, 29, as he picked up passengers at a Moorooka bus stop.

It will run in parallel with an internal review by the Metro South Hospital and Health Service.

Police have said there’s no obvious motive for the attack and have ruled out terrorism or racial factors.

Brother flies out from India to repatriate body

Amit Alisher has arrived from India and hopes to fly home with his brother’s body later this week. That’s when their frail parents will be told the heart-breaking news.

All they’ve been told so far is there’s been an accident and that Mr Manmeet is in a coma.

Indian leader Narendra Modi has phoned Prime Minister Malcolm Turnbull to express his shock and concern about Mr Alisher’s death.

O’Donohue has been charged with murder and arson, and also 11 counts of attempted murder relating to other people who were on the council bus.

Passengers who witnessed the attack and were trapped on the burning bus before taxi driver Aguek Nyok kicked out a back door have been left deeply traumatised.
