Sex crime teachers issued with lifetime bans 27 June 2013 Last updated at 14:30 Two teachers jailed for sex crimes have been banned from teaching ever again. Primary school teacher Caven Muirhead, of Clackmannanshire, sexually abused two young brothers between 1989 and 1996. IT teacher Angus McCormack, of Dundee, was caught with 7,600 images and more than 10 hours of video footage of children being sexually abused. The ban was issued by the the General Teaching Council Scotland (GTCS) at disciplinary hearings in Edinburgh. Muirhead sexually abused the young brothers when he was allowed to take them on holidays and trips after befriending their parents. The 56-year-old assaulted the pupils in caravan parks, secluded woods and in his own bedroom, while his elderly parents sat unaware downstairs. He targeted the boys over a seven-year period between 1989 and 1996 and took them on outings to Knockhill racing circuit, an RAF air show at Leuchers and Perth Leisure Pool. After gaining their trust he touched them both indecently and performed sex acts on the youngsters. Muirhead was found guilty of five charges of lewd and libidinous practices following a jury trial at Stirling Sheriff Court in November and was jailed for 18 months. Stash of images McCormack, who taught IT at Monifeith High School, Angus, was also jailed in November last year after being caught with a stash of images of child sex abuse. His computer contained material at the most serious level of the scale used by the courts, including images involving infants and children aged up to 16. McCormack was given a six-and-a-half-year extended sentence, with three-and-a-half years in jail and three on license. Both Muirhead and Caven were also placed on the sex offenders register following their convictions. 'Unfit' to teach The GTCS struck both Muirhead and Caven from the teaching register after finding both men's convictions meant they were "fundamentally incompatible with being a registered teacher" and therefore unfit to teach. Concerning McCormack, a GTCS spokesperson said: "The panel had regard to submissions that the nature of the offence and the length of the term of imprisonment indicated that the conviction is serious. The panel further noted that the respondent had been convicted on indictment. The panel observed that in his response form, the respondent accepted that 'If the facts in the complaint are proved, I agree that this means I am unfit to teach'. In light of this admission, and the fact that the panel considered that the nature of the conviction represents conduct that is fundamentally incompatible with being a registered teacher, the panel decided that the respondent falls significantly short of the standards expected of a registered teacher and is therefore unfit to teach.
