An individual who contaminated treats with tranquilliser and gave them to minors at a youth camp in Leicestershire has pleaded guilty to sexual crimes against two boys both nine and ten years old.
The defendant was detained after eight youngsters and one adult became sick at the facility in July.
The elderly man, from the Nottinghamshire area, pleaded guilty to a series of 17 offences when he stood at the courthouse on recently.
Nevertheless, he refused to admit a single sexual charge he was accused of, which was involving a nine-year-old boy.
The accused was remanded in custody before a subsequent court date on late November.
'Sweet game'
The legal representative, prosecuting, described Ruben's offending to the legal proceedings.
She stated his victims were children from difficult backgrounds who were staying at a summer camp which he managed.
Ruben conducted a "treat game" with the youngsters, the legal counsel said, in which he would enter the children's bedrooms when they were settling down and tell them to consume candy "rapidly".
She stated to the judge the man had played this game with the boys "over an extended period", and youngsters had previously become sick the subsequent day.
She stated Ruben had been able to explain this repeatedly as the children being "overwrought by enjoyment", until his stepchild had concerns in recently.
The legal representative added: "In the summer" his stepson had worries about what was going on, for good reason.
"They chose" to investigate in the defendant's belongings."
The prosecutor explained objects including infant oil, petroleum jelly and syringes were located, and his stepson alerted the law enforcement about his worries.
She explained the man continued to conduct the "sweet game" with six boys that night - Saturday 26 July - and they were all sick the next day.
"Law enforcement" had not arrived by that stage," she stated further.
The police watchdog, the police conduct office, had stated that it was investigating law enforcement's management of the events.
Mrs Prior explained the youngsters were unable to walk properly due to their condition, so the stepson notified the authorities once more.
She stated Ruben then engaged in the "sweet game" in a space of five children.
