Let me guess, some egos may have been a bit bruised here. MUST have been a harley - any other bike would have been overtaking the bus not being cut off by it..... A bus driver is in hospital and one man has been arrested following an alleged severe case of bikie road rage in South Melbourne last night. Police believe the incident occurred around 10.50pm when it is alleged a bus accidentally cut off two motorcyclists near the intersection of City Road and Market Street in South Melbourne. In retaliation, the motorcycle riders blocked the bus when it stopped at a red light. Police said one motorcyclist parked in front of the bus and the rider left his bike. It is alleged one of the riders began smashing the door and windscreen of the bus and assaulting the driver. The bus then drove forward, dragging the motorcycle, minus the rider, for a few hundred metres. The dragged bike caught fire but was soon put out by one of the motorcycle riders, who took a fire extinguisher from a nearby service station. The three passengers on the commuter bus were not injured and later transferred to another bus. Police have arrested one man for assault and criminal damage and he is currently being interviewed in St Kilda. The second rider has been released pending inquires. The bus driver was taken to hospital with minor injuries and may face possible driving charges. Police are hoping to speak to anyone who witnessed the collision. Witnesses can call Crime Stoppers on 1800 333 000.
