A person who laced candy with tranquilliser and provided them to youngsters at a youth camp in the area has admitted sexual offenses against two young males both between nine and ten.
The accused was detained after eight youngsters and one adult experienced illness at Stathern Lodge in the summer month.
The 76-year-old, from that region, admitted guilt to a multiple criminal counts when he appeared at the courthouse on Friday.
Yet, he refused to admit a single sexual charge he was facing, which was involving a young boy.
The accused was held in detention before a subsequent court date on 28 November.
'Treat game'
The legal representative, handling the case, described the defendant's actions to the judicial body.
She explained his victims were children from difficult backgrounds who were staying at a summer camp which he ran.
The man engaged in a "sweet game" with the minors, Mrs Prior explained, in which he would go into the sleeping quarters when they were preparing to sleep and request they to eat sweets "rapidly".
She stated to the judge the man had engaged in this activity with the young males "repeatedly", and children had previously fallen ill the following morning.
She explained Ruben had been successful in rationalizing this for many years as the youngsters being "overexcited from fun", until his stepchild had worries in recently.
Mrs Prior KC stated further: "In the summer" his stepson had concerns about the activities, justifiably.
"They resolved" to examine in the individual's items."
Mrs Prior KC stated materials including baby oil, ointment and medical needles were found, and his family member notified the police about his suspicions.
She stated the man proceeded to conduct the "treat game" with six youngsters that night - July 26th - and they were everyone unwell the subsequent day.
"The police had not gone out by that point," she continued.
The police watchdog, the investigative body, previously told that it was reviewing Leicestershire Police's handling of the situation.
The prosecutor said the minors were struggling to walk due to their sickness, so Ruben's stepson contacted the police a second time.
She stated the defendant then engaged in the "treat game" in a space of five youngsters.
