An individual who contaminated candy with sedative and provided them to youngsters at a summer camp in the area has pleaded guilty to sexual offences against two young males who were nine and ten years old.
The accused was taken into custody after eight children and a grown-up experienced illness at the location in July.
The 76-year-old, from the Nottinghamshire area, confessed to a series of 17 offences when he stood at the courthouse on recently.
Nevertheless, he disputed a single sexual charge he was accused of, which was against a nine-year-old boy.
The defendant was kept in jail before a additional proceeding on 28 November.
'Treat game'
Mary Prior KC, prosecuting, described the defendant's actions to the court.
She explained his targets were under-privileged children who were staying at a youth camp which he managed.
Ruben conducted a "sweet game" with the minors, the prosecutor stated, in which he would enter the sleeping quarters when they were settling down and tell them to consume candy "as quickly as they can".
She told the court the man had played this game with the boys "repeatedly", and youngsters had earlier experienced illness the next day.
She stated the man had been able to explain this for many years as the minors being "overwrought by enjoyment", until his stepchild had suspicions in recently.
Mrs Prior KC stated further: "In the summer" his stepchild had suspicions about the situation, with valid cause.
"They decided to investigate in the defendant's belongings."
The legal counsel stated items including lubricant, petroleum jelly and injection devices were discovered, and his family member notified the authorities about his worries.
She said Ruben proceeded to engage in the "candy game" with six youngsters that evening - July 26th - and they were all ill the following morning.
"The police had not arrived by that point," she added.
The oversight body, the Independent Office for Police Conduct, previously told that it was investigating the police response of the events.
Mrs Prior explained the children were struggling to walk due to their condition, so the family member called the police again.
She explained Ruben then conducted the "treat game" in a room of five minors.
