He grabbed the driver's arm and sprayed him in the face with the air can, according to documents. After the driver and passengers got off the bus, Franson sprayed a fire extinguisher inside before attempting to hijack the bus. Officials said Franson was unable to drive the bus, so he got out and faced police.
