Police have arrested four teenagers following an assault on a taxi-driver in Wollert early this morning, Victoria Police say.
The four were arrested following the assault on Bridge Inn Road at 2.45am.

As the four began to walk away the driver attempted to restrain one of the boys.
When he did this, the other three allegedly began to punch and kick the driver, inflicting serious head injuries.
Two witnesses went to the aid of the driver and contacted emergency services.
The alleged assault was still taking place when police arrived at the scene.
Police arrested the four teenagers, a 17-year-old Carlton girl, a 16-year-old Mill Park girl, a 15-year-old Coburg boy and a 13-year-old boy from Reservoir.
The four have been interviewed for a number of offences including affray, recklessly cause injury, taxi-fare evasion and assault.
