He also confessed to taking indecent pictures while visiting a nudist camp.

Ruth Smith, prosecuting, told Cardiff Crown Court that after he was arrested, the defendant said of the online images: “I have looked at terrible things.

“Think of the worst things possible and I have seen them. It’s like a drug. I have no limits – from cradle to grave.”

She added how Cwiklinski had been in contact with fellow paedophiles on social media.

Miss Smith said: “They had discussed setting up their own group.”

Cwiklinski had stored thousands of child abuse movies and stills on around a dozen electrical devices and shared more than 500 of them with others.

He had also discussed in chat rooms setting up a secret camera in the changing room of his local swimming pool.

Miss Smith said: “The indecent images are particularly extreme and involve very young children.

“Some are as young as 18 months and they show the victims in extreme distress.”

Cwiklinski pleaded guilty to distributing and making indecent images of children between March 2019 and March 2021.

The defendant’s offences were committed in the Avon and Somerset Police force area and then in Gwent when he moved to Monmouthshire.

Judge Tracey Lloyd-Clarke told the defendant: “You said there were no taboos.

“You pose a high risk of serious harm to children.”

She sentenced him to an extended prison term for the protection of the public.

The defendant was jailed for five years made up of a four-year custodial term and an extended licence period of 12 months.

Cwiklinski will have to register as a sex offender for life and be the subject of a sexual harm prevention order for an indefinite period.

The defendant admitted three counts of possessing indecent images of children at categories A, B and C.

The offences were committed between 2017 and 2020, Cardiff Crown Court was told.

He has to register as a sex offender until 2028 and was made the subject of a sexual harm prevention order for seven years.

Officers found the disturbing film following a search of the 56-year-old defendant’s home last year.

Cardiff Crown Court heard how Hoare was handed a three-year community order in 2015 for possessing indecent images of children.

The judge, Recorder Dyfed Llion Thomas, told the defendant of his most recent offence: “It was a disgusting film of a 10-year-old child being raped.

“It is of an exceptionally unpleasant nature.

“You richly deserve custody for such a despicable film.”

Recorder Thomas added: “You clearly have a sexual interest in children.”

Hoare, of Duke Street, Abertillery, admitted possessing an indecent category A image of a child on January 22, 2020.

The judge sentenced Hoare to a three-year community order.

The defendant must complete 29 sessions of the Horizon sex offender programme and a 30-day rehabilitation activity requirement.

He must observe a six-month curfew between the hours of 8pm and 6am.

Hoare will have to register as a sex offender until 2026 and was made the subject of a five-year sexual harm prevention order.

He will have to pay £720 prosecution costs and a £90 victim surcharge

The 54-year-old civil engineer was locked up after Cardiff Crown Court heard of his “shocking and disgusting” offences.

Prosecutor Jenny Yeo also told how Holland had used his iPhone to record a young girl undressing in a changing room at Abergavenny Leisure Centre.

She said police raided the home the defendant shared with his wife in December 2019.

Officers recovered child sex abuse videos and pictures, some showing victims as young as seven, stored on a desktop computer.

While analysing these sick images they came across the recordings Holland had made himself.

The defendant, of Holywell Road East, Abergavenny, pleaded guilty to two counts of voyeurism and five charges of observing a person doing a private act.

Holland also admitted three counts of making indecent images of a child.

There were for four category A, 12 category B and 196 category C images.

Karl Williams, mitigating, admitted: “Frankly these were disgusting offences.”

His barrister added: “He defendant has no previous convictions.

“The defendant wishes to apologise to his victims and he would appear to be sincere in that.

“He made full admissions and accepts the upset he has caused. The defendant is deeply ashamed for the distress he has caused.”

Mr Williams said Holland was an expert in bridge surveying and earned an annual salary of around £49,000.

He also revealed his client had worked with a community group helping refugees and asylum seekers.

Judge Michael Fitton QC told Holland: “Your own counsel describes your offences as shocking and disgusting.

“You became hooked on using pornography and chat lines.”

The judge said the defendant was in denial about being a paedophile and added: “You became attracted to young females.”

Holland will have to register as a sex offender and will be made the subject of a sexual harm prevention order.
