A woman's hair was set on fire as she rode a Community Transit bus Monday morning in Marysville.

Another passenger put out the fire before the woman was injured.

KIRO reports video shows a woman applying a flame to the hair of the woman sitting in front of her, then a man across the aisle pats it out.

The driver stopped the bus. Snohomish County deputies arrested the suspect and seized two lighters. She said it was an accident.

A Community Transit spokesman, Martin Munguia, says the woman suspected of assault is permanently excluded from bus service.
