Woman rammed off road in suspected road rage incident

A motorist was forced off the road after being rammed twice in a suspected road rage incident.

Police say the woman was driving south on Johns Rd in Christchurch around 7.45pm on Tuesday when she slowed to drive through a section of roadworks.

A white four-wheel-drive came rushing up behind her near the roundabout at Sawyers Arms Road and slammed into her rear.

"The driver reports that she braked, and skidded as her wheels locked up," says Senior Constable John Moore of the Christchurch Road Policing Unit.

The four-wheel-drive backed off before accelerating again, hitting the rear of her dark green Nissan hard for a second time.

"The impact caused the Nissan to drift sideways and onto the side of the road. The car tipped over, but fortunately landed back on its wheels without rolling over," said Mr Moore.

The woman's car came to rest about 300 metres north of McLeans Island Road, opposite The Press printing plant.

The four-wheel-drive vehicle left the scene without slowing or stopping.

It may have turned right onto McLeans Island Road.

"The driver was not hurt but was very shaken by the incident, which appeared to be totally unprovoked," said Mr Moore.

"The only thing the driver has done was to slow down - correctly - for road works.

"This incident could easily have resulted in serious injuries to the victim and to other road users."

Police believe there were two occupants in the four-wheel-drive.

The driver is described as a clean-shaven Caucasian in his 20s, and the passenger is described as a Caucasian woman of similar age, with long blond hair.

Investigators have spoken to the driver of the Nissan and to another witness, but are appealing for additional information.

"We know there were other witnesses, and we would like to hear from them as soon as possible," Mr Moore said.

"We're also seeking help from anyone who can help identify the white four-wheel-drive vehicle, or its occupants."
