A 48-year-old man is in custody in Brisbane, after the driver was doused in a flammable liquid and set on fire.

Police say the attack on the 29-year-old driver at Moorooka appears to be random and there's no suggestion it's terror-related.

Superintendent Jim Keogh says one of three people who boarded the bus on Beaudesert Road at about 9am tipped flammable liquid on the driver and then set him alight, and the other passengers are lucky to have escaped with minor injuries.

A ‘heroic’ taxi driver pushed the back door open, risking his own life, to provide an escape route to passengers trapped inside the bus.
