The Indian family of slain Brisbane bus driver Manmeet Alisher are expected to arrive in Australia to begin the process of repatriating his body.
Manmeet Alisher, 29, was burned alive when an "incendiary device" was thrown at him while he was letting passengers on at Moorooka on Friday morning.
Mr Alisher, a prominent figure and beloved singer in the Punjabi community, was employed as a casual bus driver and had only been working in the job for several months.
His brother and mother are reportedly set to arrive on Sunday to take his body back to India.
A 48-year-old man has been charged with murder, arson and 11 counts of attempted murder, and will remain in custody until his case returns to court in late November.
On Saturday, the man's lawyer said he had concerns for the mental health of his client.
Police Commissioner Ian Stewart said there was nothing to suggest the attack was racially motivated, but Mr Alisher's brother told the ABC he fears otherwise.
"We suspect that it may be [racially motivated]," Amit Alisher said.
"We would like to see due process, we have faith in the Australian system."
At a vigil in Mooroka on Saturday evening, friends said they were heartbroken over the death.
"I can't even stop crying, even now. This is really heartbreaking to us," friend Pargat Singh told the Nine Network.
Bus driver Ray Ludwigson described his colleague as a man filled with joy.
"In his face he had love and peace. It's so sad to see someone go in this way," he said.
