Courts and prosecutors said he admitted multiple offences, including sexual assault of children under 13, assault by penetration, child cruelty, making indecent images and drug offences.

The offending took place over a weekend in July 2025 and was uncovered after dozens of children fell ill and concerns were reported to police.

Judge Timothy Spencer KC described Ruben's actions as carefully planned, dangerous and causing harm "at the highest level."

Prosecutors and multiple reports describe a methodical pattern in which Ruben laced very sweet, sticky confectionery with tranquillisers bought illegally.

Using syringes and his veterinary knowledge, he administered the drug to groups of boys during a so-called 'sweet game'.

Tests on victims and on sweets identified an illegal liquid Xanax-type drug in some samples.

Several outlets report Ruben believed he had ordered temazepam from the dark web.

Investigators say he used his position in the church community and his long-standing role at the camp to gain access and trust.

Victims and their families described severe immediate and long-term harm.

Reports say eight children — and, in some accounts, ten boys in total — were taken to hospital with symptoms including vomiting, drowsiness, slurred speech and difficulty walking.

Some children were found unconscious, and one later began self-harming after discovering what had happened.

Impact statements read in court described the offences as chilling and said they caused lasting psychological damage.

Investigators uncovered a wide range of incriminating material and evidence, including syringes, baby oil, vials and other drug paraphernalia seized from Ruben’s property and camp accommodation.

His step‑son’s photographs helped trigger police involvement, and officers found large quantities of indecent images and videos on seized devices.

Some outlets reported counts for the images and noted none were of children from the camp, while others said Ruben had written to join online paedophile groups and possessed documents outlining dosing plans and lethal dosage tables.

These details underpinned the prosecution’s portrait of an offender who used expertise and planning to facilitate abuse.

Sentencing coverage records visceral reactions from victims' families and Ruben's partner.

Several sources report victims' parents called Ruben a "devious child sexual predator," and his partner described him as a "sadistic, monstrous paedophile" who had betrayed community trust; impact statements noted lasting emotional harm, including a child's self-harm.

The judge declared Ruben a dangerous offender, finding his deliberate drugging to facilitate sexual assaults warranted a lengthy custodial and licence period.
