A person who laced treats with sedative and provided them to children at a summer program in Leicestershire has confessed to sexual crimes against two children who were nine and 10.
The defendant was arrested after eight minors and an older person fell ill at the facility in July.
The elderly man, from the Nottinghamshire area, admitted guilt to a multiple criminal counts when he appeared at the judicial center on Friday.
Yet, he denied one particular crime he was accused of, which was involving a nine-year-old child.
The defendant was held in detention before a additional proceeding on 28 November.
'Candy game'
Mary Prior KC, handling the case, described the criminal behavior to the legal proceedings.
She said his victims were disadvantaged youngsters who were attending a youth camp which he managed.
Ruben played a "treat game" with the children, the prosecutor said, in which he would access the children's bedrooms when they were settling down and ask them to ingest treats "rapidly".
She informed the proceedings Ruben had played this game with the young males "for many years", and youngsters had previously become sick the following morning.
She said Ruben had been successful in rationalizing this for many years as the youngsters being "overstimulated by activities", until his stepson had worries in recently.
Mrs Prior KC continued: "In the summer" his stepson had worries about what was going on, with valid cause.
"They resolved" to examine in the defendant's belongings."
The legal counsel explained objects including infant oil, Vaseline and injection devices were found, and his stepson notified the police about his suspicions.
She stated the defendant proceeded to engage in the "candy game" with six boys that evening - that Saturday - and they were all sick the subsequent day.
"The police had not arrived by that stage," she stated further.
The regulatory agency, the investigative body, previously told that it was reviewing Leicestershire Police's handling of the incident.
The prosecutor explained the children were unable to walk properly due to their condition, so Ruben's stepson notified the authorities once more.
She explained the defendant then played the "sweet game" in a room of five youngsters.
