A teenage girl was set upon by a stranger who set her hair on fire while they were travelling on a public bus.
CCTV footage shows the 13-year-old board with a group of friends and take a seat in front of a woman wearing black clothing and sunglasses.
The woman behind the June 29 attack who police say was aged in her 50s, calmly set the teenage girl's hair alight after she sat in the seat in front of her.
Investigators are still trying to track down the woman, but believe the attack was random.
'The victim did not know this woman, there was no conversation had between them,' a South Australian police spokesman confirmed.
The footage shows the moment the teenager first realised her hair was burning.
She immediately jumped to her feet and ran to the front of the bus, followed by her group of friends.
The woman quickly slipped off the bus and out of sight of cameras.
The driver called police immediately, but investigators have not been able to track the woman down.
Officers warned there is 'already trauma attached to the incident', particularly for the young victim.
'Physical, emotional and mental trauma. That's the sort of stuff that leaves scars for a long time,' the spokesman said.
Investigators are urging anybody with information about the incident to come forward, or call Crime Stoppers on 1800 333 000.
