A “perverted” swimming instructor from south Wales has been jailed for 18 years for abusing children during his classes.
John Glyn Jones, 55, had “groomed” two young boys at Nantyglo Leisure Centre, Blaenau Gwent for five years from in the 1970s and had abused them whilst they were in his care.
Known locally as “Nipper”, he was already serving a 10-year sentence for serious sexual assaults on five boys and a girl.
A jury at Cardiff Crown Court found him guilty of 11 serious sex offences in the latest case.
The court heard Jones – of Roundhouse Close, Nantyglo – abused the swimming pupils in his office, in changing rooms, in a sunbed room, in a storeroom and in the swimming pool itself at the council-run leisure centre.
The identity of the pair abused in the 1970s was not disclosed to protect them.
Judge Christopher Llewellyn told him: “You systematically abused one of the boys from the ages of 10 until he was 15.
“It’s an understatement to say that he lost his childhood due to your perversion.
“He was forced by you to give evidence and relive the most horrifying acts.
“He was totally under your control and could not tell anyone. I have no doubt you targeted him and you then satisfied your perverted lust on him.”
Judge Llewellyn added: “The two children were put into your care and trust. You are arrogant in the way you committed the offences.”
Detective Sergeant Mark Warrender of Gwent Police said after the case: “John Glyn Jones is a dangerous sex offender who systematically abused his victims and robbed them of their innocence.”
Jones’ sentences will run concurrently and he was ordered to register as a sex offender for life and never work with children again.
