Sydney cabbie hurt in road rage attack

A taxi driver has been hit on the head with a metal bar in a suspected road rage attack in Sydney's west.

It's alleged that another vehicle cut off the taxi as it drove through Campsie and an argument took place between the two drivers, police said.

A 66-year-old man was arrested at the scene late on Wednesday and an "extendable baton" was seized.

The taxi driver was taken to Canterbury Hospital for treatment to a head wound.

His injuries are not considered life-threatening.

Police said the arrested man is expected to face charges.
