A PE teacher, who indecently assaulted pupils, was allowed to quietly resign from his job without the police being called in following a complaint he had photographed one of the boys naked.
Russell Ward then got another teaching job where he continued to sexually abuse teenage boys during coaching sessions.
At Warwick Crown Court yesterday, Ward (31), of Portland Mews, Leamington, Warwickshire, was jailed for three years and ordered to register as a sex offender for life.
Ward, who had admitted ten charges of indecent assault and asked for three other offences to be taken into consideration, was also banned from working with children.
The offences began in the late 1990s while Ward was working as a PE teacher at Pershore High School in Pershore, Worcestershire.
Simon Ward, prosecuting, said while Russell Ward had given extra tuition to boys, aged 14 and 15, and used exercises they performed as an excuse to indecently assault them. The court also heard how he secreted a video camera in a sports bag and filmed what was going on, including his indecent assaults.
Russell Ward took pictures of the boys wearing boxer shorts, saying it was to monitor their development, but it was a picture of one of them naked in the shower which led to the complaint and his resignation from the school in 1999.
In 2002, Ward got a job teaching PE in Leamington and a similar pattern of abuse developed.
"The full details did not emerge until last year when a full investigation took place, but there had been an earlier
limited complaint by one of the boys that the defendant had taken nude photographs of him," said Mr Ward.
That victim complained to his parents who took the matter up with the school, but Russell Ward was allowed to resign and the police were not notified.
"That allowed the defendant to go on with his career as a teacher and to indecently assault other young men," added Mr Ward.
The defendant was arrested in June 2004. At first, he suggested it had been a misunderstanding but then admitted what he had been doing and that he had recorded incidents for his own sexual gratification at home, adding that he was "sick and needed help".
Nick Devine, defending, said: "That reflects the confusion he has had with his own sexuality and trying to come to terms with the fact that he is attracted to men rather than women. He has never had a proper relationship with anyone, male or female."
Last night, Clive Corbett, head teacher at Pershore High School since September 2002, said: "Clearly he is not the kind of person you would want to have around children, but hindsight is a wonderful thing.
"If it happened today then we would come down on the individual concerned with the full force of the law and they would be dealt with by the police immediately and the usual disciplinary procedures would be put in place.
"I can only speak of my experience since I became head teacher, but I would give the example of the invigilators that we have just employed because each of them has undergone the most thorough and stringent checks via the Criminal Records Bureau."
