A SHOPPER has told the Old Bailey how she used her car to scare off a man who attacked a 39-year-old housewife.

Peter Anscombe is accused of committing the attack four days before allegedly knifing a teenager in Orpington.

News Shopper reported yesterday how the younger victim collapsed in the arms of a passer-by after being stabbed in an early-morning sex attack on September 30 last year.

On September 26, Helen Webbewood noticed a man following the victim in a Bromley car park.

Mrs Webbewood told the jury she had first seen the man loitering by a car park ticket machine near The Glades shopping centre in Bromley town centre.

When she reached her car on the floor below, she noticed the man was following the other shopper. She then heard screams.

The court heard the victim had been knocked to the ground and the attacker was on top of her.

Mrs Webbewood then started sounding the horn of her car and shouting at the man.

She told the jury the attacker then stood up and looked at her before slowly walking away.

Mrs Webbewood said: "He stopped doing what he was doing and began to walk away.

"Initially it was quite slow, which I found quite strange considering what he had just done. He seemed quite cool and calm."

Jurors heard Mrs Webbewood later picked out 28-year-old Anscombe in a video ID parade.

The teenage victim was attacked in Priory Gardens, Orpington, and suffered life-threatening injuries. She only survived after emergency surgery.

Anscombe is accused of following her off the bus, ripping her clothes off, groping her and stabbing her twice.

The court was told his fingerprint was found on a receipt inside the girl's purse, which was dumped in a toilet cubicle close by.

Jurors also heard the weapon, a multi-tool with two blades, was discovered in the park's pond covered in the victim's blood.

It is claimed fibres on it linked the tool to Anscombe and that CCTV caught him at or close to the scene of both incidents and following both women before they were attacked.

He claims this is a coincidence.

Jurors have already been told Anscombe is a loner obsessed with internet porn, including sites which celebrate rape and other forms of sexual violence.

Prosecutor Christopher Hehir told the court the hospital worker spent hours downloading sick stories and pictures from the internet.

He told jurors Anscombe, of Sevenoaks Way, Orpington, decided to turn a "grotesque fantasy into a reality".

Anscombe denies assault with intent to commit a sexual offence, attempted murder, causing GBH with intent, sexual assault and attempted rape.

The trial continues.
