A music teacher was jailed for two-and-a-half years today for having an affair with a sixth-former at one of the country's top grammar schools.
Married Darren Caudle-Wood, 38, seduced the shy A-level student after lessons and music practice at Pate's Grammar School, in Cheltenham.
The father of two was also accused of making passes at a number of other pupils in his and had also worked as a male prostitute.
Caudle-Wood, of Church Road, Cheltenham, denied seven charges of having sexual activity with a child under 18 while in a position of trust.
But a jury of six men and five women took just over two hours to find him unanimously guilty of all the charges.
Caudle-Wood, who was dressed smartly in a pinstripe suit, showed no emotion as the foreman delivered his verdict at Gloucester Crown Court.
In sentencing Caudle-Wood, Judge Martin Picton said he had stolen part of the girl's childhood.
"In my view this was genuinely wicked behaviour on your part because you misused your position of trust you were in."
"The knowledge you had of [her] background, naivety and difficulties to manipulate her and to seduce her.
"I suppose in a way that totally ignored her rights and her sensitivities and in a way that was utterly selfish and very damaging for her.
"I only have to watch her give evidence to see the damage it has caused. You stole part of her childhood. She was very vulnerable, you knew that and you treated her in an utterly shoddy way and in an utterly selfish way.
"You have utterly failed to understand the boundaries which should apply in a teacher-pupil relationship. You have failed to act in a way a teacher should and you have failed to act in a way a decent human being should. You let down your wife, her family and you have let down yourself."
The judge told the teacher that he had "taken his chances" and gambled on being found not guilty by a jury even though the evidence against him was "overwhelming".
He said Caudle-Wood would have to serve at least half his two-and-a-half year jail term but would also face an extended period of licence of a further two and a half years.
He was also disqualified from working with children under the age of 18 and told to sign the Sex Offenders Register for life.
His wife Rose, with his father Victor and mother-in-law, watched from the public gallery as the sentence was passed down.
The victim, who cannot be named for legal reasons, was studying at the highly-rated school, where Caudle-Wood had been director of music since 1999.
He was soon inviting the 17-year-old into his office after , where they discussed their mutual love of Wagner and how he could help her get into Oxford University.
They began meeting in secret after rehearsals for the school play, Christmas carol concerts, music lessons and even after an exam. They would kiss, hug and Caudle-Wood frequently made sexually explicit remarks to her during their eight-month affair.
He told the vulnerable teenager, who suffered from depression, that he loved her and asked her to be his girlfriend, claiming his marriage was over.
Caudle-Wood, who described himself as an "old-fashioned" teacher, later persuaded the girl to meet him in a B&B room where a prostitute friend had prepared a candle-lit setting in a brothel.
The girl said she had been terrified, but agreed to get into bed with her teacher who she now "cared for deeply".
The couple were sexually intimate but it fell short of full intercourse, the jury heard.
Caudle-Wood, who sat on the school's Oxbridge Admissions Board, had already been investigated by police over claims that he had an inappropriate relationship with a pupil at another school in 1993. Despite facing no charges, he left by "mutual agreement" shortly afterwards.
As his affair with his A-Level student began to flourish, Caudle-Wood was already building up his defence in case he was caught out.
He informed the headteacher that the teenager had a crush on him and was sending him inappropriate text messages.
Their affair only became public after the teenager was summoned to see the headteacher to explain why she had been harassing Caudle-Wood.
She then confessed that they had been having a relationship.
Caudle-Wood was arrested in October 2005 but claimed she was a fantasist. But three other pupils - including a male sixth-former - also told how he had kissed them and invited them back to his flat.
More damaging details of his private life also emerged during the trial, including claims that he worked as a male prostitute and had used heroin.
Judge Picton praised the evidence given by Donna Harding, the prostitute who had "bravely" testified against the once-respected music teacher.
He said: "She was in a very difficult position when she exposed her history to the public by having the courage to tell the true story of this case."
Harding, 29, who is battling drug addiction, was awarded £250 by the judge in recognition of having come forward.
