A retired maths teacher who taught at a Norfolk school has been jailed for five years for sexually abusing two boys more than 30 years ago.

At the time of the offences in 1977 and 1980 Alan Brigden was teaching at a boys' boarding school in Sussex and then at the former St George's School, which was based in Wicklewood, near Wymondham, before moving to Great Finborough, near Stowmarket.

Brigden, 67, who has been living in Amsterdam, was extradited from Holland in January following an inquiry into the former St George's School which led to former headmaster Derek Slade being jailed for 21 years in 2010 for sexually and physically abusing pupils.

Brigden admitted four offences of assault with intent to commit serious sexual assault, four offences of indecency with a boy under the age of 14 and six offences of indecent assault on a boy under the age of 14.

Jailing him for five years, Judge Rupert Overbury described the offences as a gross breach of trust.

He gave Brigden credit for pleading guilty to the offences and sparing his two victims the ordeal of coming to court and 'reliving the horrors of their childhood'.

Jan Brewer, prosecuting, said that in 1977, while Brigden was teaching at a school in Sussex, he had taken the victim and two other boys on holiday to the Lake District and while there had groped him. The boy had slapped Brigden's hand away and on his return to school had told the matron what had happened.

Brigden left the school in Sussex and by 1979, using the name Morton, he was teaching at the former St George's School at Wicklewood. There he befriended an 11-year-old boy and took him on a 10-day train trip around England and Wales during which he sexually assaulted the boy every night while they slept on the train.

Miss Brewer said the boy had not liked what was happening to him and had asked to go home. She said the situation had been confusing for him as Brigden had been nice to him during the day but every night was like 'a bad dream or nightmare'.

Miss Brewer said clothing belonging to the boy were recovered from Brigden's home.

Nicholas Bleaney, for Brigden, said his client suffered from Parkinsons Disease.

He said there was no evidence Brigden had re-offended in the years following the offences the court had heard about.
