Police have spoken to witnesses and are looking for the driver or owner of the vehicle involved.

91原创 City fire fighters responded to give medical aid to the people exposed to pepper spray.

鈥淭here were a lot of people who had awfully red faces,鈥� said City fire chief Rory Thompson.

Several people commented on the 91原创 Advance鈥檚 that they had been hit with the pepper spray.
