A games teacher has been jailed for four years after he admitted committing a sex act on a pupil.
Games teacher Neil Binder was jailed for four years
At an earlier hearing, Neil Quentin Binder, 43, who now lives in Buckinghamshire, admitted sexually touching a boy under the age of 16.
Judge Jonathan Haworth at Cambridge Crown Court described the offence as "dreadful".
The school where the incident took place cannot be identified for legal reasons.
Prosecutor Sara Walker told the court that Binder had committed the offence in his flat on school premises.
Afterwards he had tried to persuade the boy to stay quiet about what had happened.
"He said it was only a bit of sex. He asked the victim 'please don't tell anyone. It can just be between you and me'," Miss Walker said.
Binder had already left the school by the time the boy made his complaint.
Claire Matthews, defending, said that Binder was aware of the gravity of his offence and was being treated for depression.
Police and the school praised the bravery of the boy who reported the offence after reading on the internet about child abuse.
A spokesman for the school where the offence occurred said: "It is immensely shocking to such a caring community that a member of the school's staff could have abused a child.
"The courage of the victim in speaking out about this act of abuse cannot be praised too highly."
He said it set a "wonderful example" to children who may find themselves in similar circumstances.
"Such courage, which has prevented the possibility of further harm to children by Neil Binder, is to be deeply respected."
The spokesman said appropriate references and relevant criminal background checks were undertaken before Binder started work.
Judge Haworth told Binder: "Goodness knows the effect upon him in the long term."
He said Binder would be eligible for parole after serving two years of his sentence.
He also said Binder must never work with children again and must sign the Sex Offenders' Register on his release from prison.
