Hubert Hallman, 82, admitted four counts of indecent assault against a pupil while he was a French teacher at the Stroud School in Romsey, Hampshire.

Southampton Crown Court heard his “traumatised victim” came forward in 2017 following high-profile child sex abuse cases.

Hallman was given a jail sentence of two years and six months.

The court heard Hallman, of Highfield Lane, St Albans, was regarded as a “ferocious school master” and pupils at Stroud School were “terrified” of him.

Addressing Hallman as he passed sentence, Judge Robert Pawson said: “Have you actually thought deeply about the damage you’ve caused someone else?

“Nothing can undo what you did to that little boy – it led to significant consequences. It is never too late for a victim’s pain to be recognised and your guilt to be punished.”
