Police are calling for witnesses to a shocking road rage incident on the Tonkin Highway last week.
Four men started brawling on the busy road about 3:30pm on Wednesday following a minor traffic incident.
Bottles and a piece of plastic conduit were used as weapons in the fray.
One man jumped feet-first into a car before it sped about 30 metres up Tonkin Highway.
Horrified onlookers caught the incident on film, but police are hoping more witnesses will come forward.
Anyone with information should call Crime Stoppers on 1800 333 000.
