Video shows woman's hair being set ablaze on MUNI bus

The San Francisco Police Department hopes newly released surveillance video will help catch the person who set a Muni passenger's hair on fire.

Video of the May 2 incident captures what happened on the #5 Fulton Street bus as it traveled on McAllister Street near Leavenworth Street.

A woman can be seen sitting in a row to herself with someone seated behind her who appears to have a lighter in his hand.

It's unclear if any words were exchanged between the victim and suspect at any point as the video does not show that, but seemingly out of nowhere the suspect sets the woman's hair on fire.

Officers from the Tenderloin station were called to the scene, but by the time they got there, the suspect and his two friends had fled the scene.

Other Muni passengers assisted the victim who then left the scene before police arrived.
