Ex-teacher Coatman accused of having sex with boy (14)
A retired headmaster had sex with a 14-year-old boy he met through a Christian youth group around 40 years ago, a court heard.
John Coatman (75) is on trial at the Old Bailey charged with buggery and two counts of gross indecency with a youth over a 12-month period in the 1970s.
At the time of the alleged offences, Coatman was headteacher of St Andrew's secondary school in Croydon, south London, as well as being involved with the Christian group for boys, prosecutor Corinne Bramwell told jurors.
She told how "rough and tumble" turned sexual when the defendant was alone with the boy, who cannot be named for legal reasons.
Although the alleged victim said he was not "entirely comfortable" with what happened, he did not report it to police until 2014, the court heard.
The catalyst was the breakdown of his marriage after his wife found out that he was watching pornography and meeting adults online, as well as work problems, the court heard.
In a videoed police interview played to the court, he told how he had been bullied before joining the Christian group which gave him a "sense of a home" away from his family.
He wept as he told an officer: "It was my first sexual experience and has coloured my sense of self-worth since then."
Coatman, of Leyburn Gardens, Croydon, denies the charges against him.
