Pupils drank washing up liquid to make themselves sick to avoid teacher who sexually abused them in front of the whole class Ronald Wotton, 73, jailed for five years at Teesside Magistrates Court Convicted of stream of abuse including 17 counts of indecent assault 'Allowed' to retire in 1980 after headmaster could not ignore allegations His wife left him and 'lived in miserable isolation for 30 years' fearful his crimes would be uncovered One abused pupil who told headmaster was forced to apologise to Wotton when she was not believed Wotton has inoperable cancer of the colon and groin Pervert: Ronald Wotton called pupils to the front of the class where he abused them behind his desk Primary school pupils made themselves sick with washing up liquid to try to avoid lessons with a teacher who sexually abused them in front of the whole class, a court has heard. When one child complained about Ronald Wotton, the headmaster at the Roman Catholic school did not believe that the allegation and made the pupil apologise to the abuser. Judge Howard Crowson, sitting at Teesside Magistrates Court, jailed the terminally-ill 73-year-old for five years. Wotton who sometimes uses a wheelchair admitted 17 counts of indecent assault, three counts of indecency with a male and one of indecency with a child over a 12-year period from the late 1960s. He was allowed to retire in 1980 when a new headmaster, who could not ignore the mounting allegations against the teacher, took over. Judge Crowson told Wotton, of Seaham, County Durham: "You were sadly operating at a time when, to most of the adult public, it was inconceivable for this type of offending to be committed by a teacher." Wotton's wife left him when he was forced to retire and he has lived in miserable isolation for 30 years, fearful that one day he would be prosecuted, the court heard. The police began investigating last year when one of his victims was inspired to speak out amid the publicity surrounding the Sir Jimmy Savile scandal, the judge heard. Detectives went to the school, which is not being identified to protect the anonymity of complainants, and traced Wotton's pupils, kicking off an extensive investigation. Joanne Kidd, prosecuting, said that 27 made formal statements and 20 of them were represented on the indictment. One victim, now middle-aged, said Wotton was an authoritarian, strict and a bully who set his classroom out so he was behind a "huge desk" in front of the children. He would catch a child's eye, ask them to come forward and while hidden behind the desk, he would sexually abuse them over their clothes while he asked in a low and sinister voice if their parents spanked them, the court heard. Wotton would rub his groin as he did so. Some complainants recalled almost daily abuse. Ronald Wotton arrives at court before getting into his wheelchair to be pushed into court and then prison He would make children bend over in PE classes and stare at them and watch them get changed for swimming. It made for an "extremely abnormal" atmosphere in lessons, as children would keep their heads down to avoid making eye-contact with him. When one pupil "took the brave step" of informing the headmaster what was happening to her, the adult called her a "bold girl" and remonstrated with her, saying: "Mr Wotton would not do such things." You were sadly operating at a time when, to most of the adult public, it was inconceivable for this type of offending to be committed by a teacher Miss Kidd said: "She forced her to go back to the classroom and apologise to Mr Wotton in front of the whole class." Children would rarely tell their parents, but on occasions furious adults would go in to school and confront Wotton. But nothing was done and he carried on. Miss Kidd said: "Many of the complainants began to feign illnesses and in some cases swallow washing up liquid in order to vomit and avoid having to go to school." The headmaster told one parent who had complained that the behaviour was "just Mr Wotton's way of being friendly," Miss Kidd said. The judge said: "No doubt she believed it, unfortunately." The court heard the washing up liquid tip was passed down by older siblings to younger pupils who were warned about Wotton. Woolton makes as if to throw his suitcase at those waiting to see him sentenced for his heinous crimes The teacher abused boys and girls, the judge, who sat at Teesside Magistrates" Court because of its wheelchair accessibility, was told. One pupil said his way of avoiding the abuse was truancy, and as a result he missed out on "a significant amount of basic education" which he never caught up, the prosecution said. When he was arrested, Wotton said the abuse had not happened and he retired due to his deafness. But Miss Kidd said in reality he was "invited to retire" after the new headmaster had a discussion with the parish priest. "It was obviously dealt with in a very informal way," she said. The judge was handed statements from victims, two of which were read out in court. One expressed bitterness towards the Catholic Church, saying: "They should have been there for us and should have listened." Many of the complainants began to feign illnesses and in some cases swallow washing up liquid in order to vomit and avoid having to go to school Joanne Kidd, prosecuting She never told her staunchly Catholic parents as to have done so would have felt like betrayal. Another said: "It was a Catholic school and the culture was teachers were right and you did what you were told." Tony Hawks, defending, said Wotton had been a pariah since he retired at a young age and had not worked again. He lived miserably and alone, the barrister said. "The defendant is thoroughly ashamed and disgusted by his behaviour," he said. Wotton has inoperable cancer of the colon and groin and earlier this year he had been expected to die. He also has heart and digestive conditions and is profoundly deaf. The judge said children had not been believed and that allowed Wotton's offending to continue. "That you felt able to operate in this manner in front of a classroom of children is reprehensible," he said. The abuse was aggravated by him continuing in the face of "direct challenge," the judge said. He jailed him for five years and imposed an indefinite Sexual Offences Prevention Order and a ban on him having contact with children without social services authority
