An individual who contaminated candy with sedative and provided them to children at a summer program in the region has admitted sexual offenses against two young males who were between nine and ten.
The accused was detained after eight children and one adult fell ill at the facility in July.
The senior citizen, from the Nottinghamshire area, admitted guilt to a series of 17 offences when he was present at the courthouse on Friday.
Nevertheless, he denied a single sexual charge he was accused of, which was involving a nine-year-old boy.
Ruben was remanded in custody before a further hearing on late November.
'Sweet game'
The legal representative, handling the case, outlined the defendant's actions to the judicial body.
She said his those affected were disadvantaged youngsters who were participating in a summer camp which he managed.
Ruben conducted a "treat game" with the minors, the legal counsel explained, in which he would enter the children's bedrooms when they were getting ready for bed and request they to eat sweets "as quickly as they can".
She told the court the defendant had engaged in this activity with the children "over an extended period", and minors had earlier experienced illness the subsequent day.
She said the defendant had been successful in rationalizing this for many years as the youngsters being "overwrought by enjoyment", until his stepchild had concerns in recently.
The prosecutor stated further: "This year his stepson had worries about what was going on, for good reason.
"They decided to examine in the defendant's belongings."
Mrs Prior KC stated materials including baby oil, Vaseline and injection devices were discovered, and his family member alerted the law enforcement about his worries.
She explained the man continued to conduct the "sweet game" with six boys that time - July 26th - and they were everyone unwell the next day.
"The police had not responded by that point," she added.
The police watchdog, the police conduct office, earlier informed that it was examining Leicestershire Police's handling of the situation.
The prosecutor said the youngsters were struggling to walk due to their sickness, so Ruben's stepson called the authorities a second time.
She said the defendant then conducted the "candy game" in a room of five children.
