An individual who contaminated treats with tranquilliser and gave them to children at a youth camp in the area has confessed to sexual offences against two boys both nine and ten years old.
The accused was taken into custody after eight children and one adult became sick at the location in mid-summer.
The senior citizen, from that region, admitted guilt to a multiple criminal counts when he was present at the judicial center on the end of the week.
Yet, he refused to admit one of the sexual offences he was facing, which was concerning a nine-year-old child.
The accused was remanded in custody prior to a subsequent court date on late November.
'Candy game'
Mary Prior KC, prosecuting, outlined the defendant's actions to the judicial body.
She explained his victims were children from difficult backgrounds who were attending a youth camp which he managed.
Ruben conducted a "candy game" with the youngsters, the prosecutor explained, in which he would access the children's bedrooms when they were getting ready for bed and tell them to ingest treats "as quickly as they can".
She told the court the man had engaged in this activity with the young males "over an extended period", and minors had earlier experienced illness the following morning.
She said the defendant had been capable of justifying this over a long period as the children being "overstimulated by activities", until his family member had worries in recently.
Mrs Prior KC continued: "Recently" his stepchild had concerns about the situation, justifiably.
"They decided to have a look in the defendant's belongings."
The prosecutor explained items including infant oil, Vaseline and injection devices were discovered, and his family member alerted the police about his concerns.
She said Ruben continued to engage in the "candy game" with six youngsters that evening - that Saturday - and they were all sick the subsequent day.
"Law enforcement" had not gone out by that time," she continued.
The oversight body, the police conduct office, earlier informed that it was reviewing Leicestershire Police's handling of the incident.
The legal representative said the children were unable to walk properly due to their sickness, so Ruben's stepson contacted the law enforcement again.
She stated the defendant then played the "sweet game" in a room of five minors.
