A former family care officer at a G4S immigration detention centre repeatedly raped a woman over a two-year period, a jury has heard.

Scott Webster, 27, from Brier Road, Tadworth, faces 16 charges, including twice chipping the alleged victim's tooth during assaults, raping her, and biting her with sufficient force to break the skin.

Mr Webster denies the allegations and pleaded not guilty to all charges at Croydon Magistrates' Court on May 10, 2016.

On one occasion Mr Webster held a knife to his victim's throat and told her he would kill her, Croydon Crown Court was told on the second day of his trial.

Prosecuting, Mr Simon Gledhill said: "This is a case about prolonged abuse which was both physical and sexual."

The offences are said to have taken place between 2011 and 2013.

Mr Gledhill also told the court that Mr Webster started using restraining holds on the victim, who can not be named for legal reasons, which he learned while training as a family care officer at a immigration detention centre run by G4S. He left the security firm in 2013.

Giving evidence centre from behind a screen, the victim told the court that while raping her: “He held my waist and said, ‘I will be quick. The more you move, the more it will hurt.’”

She also told the court that Mr Webster's attacks were carefully targeted on parts of her body that "you couldn't really see".

"I was always covered in bruises and had grab marks on my legs and arms," she said.

"I was stupid. I often thought I deserved it and made it happen."

She kept her bruises hidden from friends and family with long clothing, even during hot summer temperatures, Mr Gledhill told the court.

But she progressively began to confide in her sister after she reported Mr Webster to the police for biting her on the nose. Mr Webster admitted this and was issued with a caution.

Mr Webster was later arrested on September 28, 2014.

He denies all charges.

Defending, Miss Clare Dowse addressed the court on Wednesday. Speaking "on behalf of Scott Webster", she said: "What you (the victim) have said about him is not true.

"He did not assault you, except for one the occasion when he accepted a caution.

"He has never forced you into sex of any kind and has never penetrated you without your consent."

Miss Dowse asked the victim: "It's all lies, isn't it?

"You have made these allegations up, haven't you?"

The victim responded: "No, that is not true."

Miss Dowse questioned why the victim did not tell the police about the alleged rapes and attacks when she told the police about Mr Webster biting her on the nose.

“You had an opportunity to complain to the police about him at that point – but you didn’t,” she said.

“I suggest that is because none of these allegations you are now making are true.”

The victim again replied this was not the case.

The trial continues.
