A woman and her elderly mother were allegedly repeatedly punched by a man during a road rage incident in Sydney's west earlier this month.
Police say a 77-year-old woman was driving in Blacktown on May 4 when a man driving a 4WD behind her honked his horn when she failed to drive through an intersection because of safety concerns.
It's alleged the 40-year-old man walked up to the car at the following intersection and began hitting the passenger window and door.
He then opened the door and punched a 58-year-old woman in the face a number of times.
The 77-year-old woman was also allegedly punched in the arm as she tried to protect her daughter.
