An individual who laced sweets with sedative and gave them to youngsters at a youth camp in the area has confessed to sexual crimes against two boys who were nine and ten years old.
The defendant was taken into custody after eight youngsters and a grown-up became sick at Stathern Lodge in the summer month.
The 76-year-old, from that region, admitted guilt to a series of 17 offences when he was present at the judicial center on the end of the week.
However, he denied one of the sexual offences he was accused of, which was against a young boy.
The defendant was held in detention before a further hearing on November 28th.
'Candy game'
Mary Prior KC, prosecuting, outlined the criminal behavior to the court.
She said his targets were children from difficult backgrounds who were attending a summer camp which he ran.
Ruben engaged in a "candy game" with the youngsters, the legal counsel said, in which he would go into the children's bedrooms when they were getting ready for bed and tell them to eat sweets "rapidly".
She told the court the man had played this game with the young males "over an extended period", and youngsters had previously become sick the subsequent day.
She explained Ruben had been successful in rationalizing this repeatedly as the children being "overwrought by enjoyment", until his family member had worries in recently.
The legal representative added: "In the summer" his family member had concerns about the situation, for good reason.
"They chose" to have a look in the man's possessions."
Mrs Prior KC explained objects including infant oil, Vaseline and injection devices were located, and his stepson contacted the law enforcement about his worries.
She explained the defendant continued to conduct the "treat game" with six youngsters that evening - July 26th - and they were everyone unwell the subsequent day.
"Law enforcement" had not responded by that stage," she added.
The police watchdog, the Independent Office for Police Conduct, earlier informed that it was investigating Leicestershire Police's handling of the events.
The legal representative said the children were unable to walk properly due to being ill, so the family member notified the law enforcement again.
She stated the defendant then played the "candy game" in a room of five children.
