A heavily pregnant woman was bruised, shaken and her baby endangered after a road rage incident caused a car to crash into her own stationary vehicle.
A man was seen pounding on a black car in Christchurch on July 18.
As the driver of the black car tried to drive away, the man continued to hit his roof and windows.
The driver of the black car then heavily accelerated in reverse, missing the car behind it, and driving across a lane and into the side of another car in the next lane.
The crash caused some damage to this car and bruising to the pregnant driver, who had been stationary in her car and waiting for the traffic signals to change.
Police said the woman was badly shaken up which could have had serious implications for her pregnancy.
She was assessed in hospital and, fortunately, there were no issues.
The black car fled across the median and travelled south on Ensors Road.
The attacker who had been hitting the car got into an unknown vehicle and travelled north onto Aldwins Road, ahead of a cream or white flat-deck truck.
Police would like to hear from the driver of the black car and anyone else who can identify the attacker or his vehicle.
Businesses and individuals in the area with CCTV are asked to check for any evidence of the truck and the vehicle ahead of it on Aldwins Road.
