A MAN persuaded teenage girls into sex poses on the internet.

And Darren Roberts then went on to have sex with one of the youngsters – aged just 13.

Now the Primrose Hill man who persuaded the two teenage girls to pose indecently for him using internet webcams has been jailed for four years.

The 24-year-old was yesterday described by a judge as ‘’devious and deviant’’ with an attraction for girls much younger than himself.

Judge Jonathan Durham Hall QC emphasised that it was not a case of love and genuine affection leading naturally to intimacy, but one of grooming.

Bradford Crown Court heard that the man became attracted to one of the girls when she was just 13.

“Following internet, MSN and webcam contact, you really set you sights on her,’’ the judge said.

“That young girl was only 14 and she indicates in her victim impact letter the extent of your activities .... you making her feel loved and wanted and your endearments.

“The persuasion to show herself on the webcam and her beginning to think it was completely normal to take her clothes off in your mechanical presence.

“She clearly fell for you hook, line and sinker and now realises what you have done.”

The court heard how the defendant, of Lawton Street, and the girl performed sex acts and also had sexual intercourse during their prolonged relationship.

Following the man’s arrest he talked about it being a loving and consensual relationship.

But when his computer was analysed police found a number of indecent images of other teenagers.

The defendant pleaded guilty to four charges of sexual activity with a child and two of causing or inciting a child to engage in sexual activity.

He also admitted six specimen allegations relating to the making of indecent images of children.

Judge Durham Hall told the man that he would be subject to an indefinite sexual offences’ prevention order and would also have to register as a sex offender with the police following his release from prison.

He was also banned from seeking any sort of employment which could involve contact with youngsters.
