Teacher Derek Lloyd 'abused pupil at school in Cornwall'
A teacher groomed and sexually abused a young boy at a boarding school for children with behavioural problems, a court heard.
Derek Lloyd, 70, allegedly abused a teenage boy at a school in Cornwall between 1978 and 1981.
The English teacher indecently assaulted the pupil in his library at the school and on a camping trip, the court heard.
Mr Lloyd denies three charges of indecent assault against a child.
David Sapiecha, for the prosecution, told Truro Crown court Mr Lloyd was described as being "mature, cultured and intelligent" in the eyes of pupils.
He said Mr Lloyd was "a responsible person, somebody who should take responsibility and not act on his own selfish sexual desires".
The court heard Mr Lloyd, of St John's Court, Stratford-upon-Avon, would invite the victim to his rooms to read books, drink coffee and listen to music.
Mr Sapiecha said children at the school were "vulnerable emotionally".
In video evidence shown to the jury, the victim described the abuse as "a disgusting event in my life".
He said it had been a "dark dirty secret" and he had not previously told anybody of what happened.
The abuse happened when the victim was aged between 13 and 15, prosecutors said.
The trial continues.
