A teenage girl has described to a jury how she was left feeling "dirty and uncomfortable" after she was sexually assaulted by her dentist.

The youngster has alleged that Dr Muzzafar Zaman groped her chest after he had given her gas and air at an after-hours appointment at his surgery on High Street in Brighouse.

A jury at Bradford Crown Court were played a video interview the girl, who cannot be identified for legal reasons, gave to the police after making the allegations in February last year.

In it she said Zaman, who denies a charge of sexual assault, had asked her if he could try out a new technique before sitting her in his chair and giving her the gas and air.

"He started rubbing his hands up and down my arms and putting his hands on my stomach and said 'breath deeply' and then raised his hand across my chest, all down my chest and my arms," she said.

"I did not really feel safe, but I did not say anything because I was too scared."

The girl, who had turned 16 just a few weeks before the alleged incident, said she was feeling woozy and was struggling to keep her eyes open when Zaman reduced the mixture and she got out of the chair.

But she wept as she described in her interview how her dentist of five years then put his arm around her waist as he was showing her some x-rays of her teeth that she had already seen.

"He started cuddling me, putting his hands around my waist. He was telling me the same things he told me at the last appointment which I already knew and he kept pulling me close to him."

Asked by the interviewing officer how it made her feel, she replied: "When it happened I just felt dirty, I did not feel comfortable. It has totally put me off going there again, I do not want to go back."

When she finally got out of the surgery the girl said that she was too scared at first to tell anybody what had happened but told her mum later that night because she did not want anybody else to go through what she had.

The jury have been told Zaman, 40, of Central Park, Saville Park, Halifax, had purposely changed her appointment to a time when he knew they would be alone and was grooming the girl.

But the defendant denies deliberately engineering the situation, claiming his secretary had gone home sick that day.

Zaman admitted to the police he kept no record of the appointment and had not followed the rules that govern administering gas and air, but denies sexually assaulting the girl.

The trial continues.
