A mother allegedly tried to mow down a cyclist and ploughed into a hair salon in her Audi 4x4 after an argument in a Kingston street, a court has heard.

Natalie Pyne, 31, of Mount Pleasant Road, New Malden, is accused of attempted grievous bodily harm after driving into autistic Simon Edgley in Park Road on June 7 last year.

Kingston Crown Court heard this afternoon how Mrs Pyne got out of her car and had an argument with cyclist Mr Edgley after an alleged near miss between the two.

Mr Edgley is said to have kicked her white Audi Q7 after which Mrs Pyne allegedly reversed her car, aimed at the victim and attempted to run him over.

Witnesses described seeing Mr Edgley "roll over" the bonnet of the car before it smashed through the Park Salon window.

Louisa Morris, who had been in her parents’ house opposite at the time of the crash, told the court: "There seemed to be an argument about a potential collision.

"I remember hearing loud revs of an engine and then tyres squealing. "It all happened very fast.

"The cyclist was hit by the front of the car and pushed off his bike. He rolled over the bonnet coming off the side."

Anna Best had been waiting at the junction of New Road and Park Road next to the salon.

She told the court she saw an argument between Mrs Pyne and Mr Edgley and a teenage boy in the Audi shout at the victim who "kicked the car multiple times."

She said: "A boy, who I assume was her son, started to have a go [at the cyclist.] "He [Mr Edgley] was kicking the car in quite a comical manner.

"The lady who was driving was quite aggressive in her behaviour."

After Mr Edgley started to cycle off Mrs Best recalled seeing the defendant reversing before driving towards the cyclist and into the salon.

She said: "I just remember thinking why are you reversing? She was moving in an aggressive manner. I was really shocked."

Mrs Pyne denies attempted GBH, dangerous driving and destroying property.

The trial continues.
