Riders on a Kansas City bus where a woman sprayed a half-dozen people with gasoline and threatened to start a fire said the 32-year-old suspect was angry that another passenger wouldn't move.
The Kansas City Star reported the incident happened around 5:30 a.m. Monday on a Metro bus that travels an especially busy route.
Passenger Randy Harris said the woman demanded that a man who sat down next to her move. Witnesses said when the man refused, the woman pulled a plastic bottle from her bag and splashed him with gasoline that also hit five nearby passengers.
Police and passengers said the woman also tried unsuccessfully to light matches, and threatened people with a steak knife.
None of those hit by gasoline needed hospital treatment. The woman was arrested.
