An individual who contaminated treats with sleeping medication and gave them to youngsters at a youth camp in the area has admitted sexual offences against two children who were nine and ten years old.
The defendant was arrested after eight youngsters and a grown-up experienced illness at Stathern Lodge in July.
The senior citizen, from the Nottinghamshire area, confessed to a series of 17 offences when he was present at the judicial center on Friday.
Nevertheless, he disputed a single sexual charge he was charged with, which was against a nine-year-old boy.
The defendant was kept in jail ahead of a subsequent court date on 28 November.
'Treat game'
The legal representative, presenting evidence, outlined the defendant's actions to the judicial body.
She stated his victims were under-privileged children who were staying at a summer camp which he operated.
The man played a "sweet game" with the children, the legal counsel explained, in which he would enter the boys' rooms when they were getting ready for bed and tell them to eat sweets "as quickly as they can".
She informed the proceedings the defendant had conducted this practice with the children "over an extended period", and children had previously fallen ill the subsequent day.
She stated Ruben had been successful in rationalizing this repeatedly as the children being "overwrought by enjoyment", until his family member had concerns in summer 2025.
The prosecutor added: "Recently" his stepchild had worries about the situation, with valid cause.
"They resolved" to examine in the defendant's belongings."
Mrs Prior KC stated items including baby oil, ointment and medical needles were discovered, and his stepson notified the police about his worries.
She said the defendant continued to play the "sweet game" with six youngsters that evening - July 26th - and they were all ill the next day.
"Law enforcement" had not responded by that stage," she continued.
The regulatory agency, the Independent Office for Police Conduct, had stated that it was investigating Leicestershire Police's handling of the situation.
The prosecutor explained the youngsters were unable to walk properly due to being ill, so the family member contacted the law enforcement a second time.
She explained the man then conducted the "sweet game" in a space of five minors.
