A person who contaminated treats with tranquilliser and provided them to children at a summer program in the region has confessed to sexual crimes against two children both nine and 10.
The defendant was detained after eight youngsters and an older person fell ill at Stathern Lodge in the summer month.
The elderly man, from that region, confessed to a multiple criminal counts when he was present at Leicester Crown Court on Friday.
However, he refused to admit a single sexual charge he was charged with, which was involving a young boy.
Ruben was held in detention ahead of a subsequent court date on late November.
'Treat game'
The prosecutor, handling the case, described the criminal behavior to the judicial body.
She said his those affected were children from difficult backgrounds who were attending a youth camp which he operated.
Ruben conducted a "sweet game" with the minors, the legal counsel said, in which he would go into the children's bedrooms when they were getting ready for bed and request they to eat sweets "rapidly".
She told the court Ruben had engaged in this activity with the young males "over an extended period", and youngsters had previously fallen ill the following morning.
She explained the man had been successful in rationalizing this over a long period as the minors being "overstimulated by activities", until his stepson had worries in recently.
The legal representative stated further: "Recently" his family member had worries about the situation, with valid cause.
"They resolved" to have a look in the man's possessions."
The prosecutor stated objects including lubricant, petroleum jelly and injection devices were discovered, and his family member notified the authorities about his worries.
She stated the man continued to conduct the "treat game" with six boys that evening - July 26th - and they were all sick the subsequent day.
"Law enforcement" had not responded by that time," she continued.
The police watchdog, the Independent Office for Police Conduct, earlier informed that it was examining Leicestershire Police's handling of the events.
The prosecutor explained the children were struggling to walk due to their sickness, so the family member notified the authorities a second time.
She explained Ruben then engaged in the "candy game" in a space of five youngsters.
