A woman has been arrested after allegedly setting fire to a teenager's hair on a bus in Adelaide's northern suburbs earlier this year.
The incident occurred along Heytesbury Road in Davoren Park on June 29 and was unprovoked, SA Police said.
An investigation by police, with assistance from the public, has led to the arrest of a 49-year-old Davoren Park woman.
She has been charged with aggravated assault causing harm.
Footage from the time of the incident shows a woman entering the bus at the Elizabeth Shopping Centre Interchange.
The woman sits directly behind the victim before reaching over the seat and setting her hair alight.
A friend of the victim helped to extinguish the fire which left the teenager with minor burns to her scalp.
The Davoren Park woman has been banned from using public transport for three months and will face the Elizabeth Magistrates Court in December.
It follows other incidents on Adelaide's public transport this year including alleged physical and racial attacks on passengers and drivers.
Passengers on board a bus in Glenelg East were left terrified and forced to duck for cover as a man used roadworks equipment to smash windows on a public bus in June.
Footage of another altercation in August circulated on social media showing a young man verbally abusing three young women.
