An individual who spiked treats with sleeping medication and provided them to minors at a youth camp in the area has admitted sexual crimes against two children aged between nine and ten.
The accused was detained after eight minors and an older person fell ill at the location in the summer month.
The elderly man, from the Nottinghamshire area, confessed to a series of 17 offences when he stood at Leicester Crown Court on the end of the week.
Nevertheless, he disputed a single sexual charge he was accused of, which was against a nine-year-old child.
The accused was remanded in custody prior to a further hearing on late November.
'Treat game'
Mary Prior KC, handling the case, detailed the defendant's actions to the judicial body.
She explained his targets were disadvantaged youngsters who were participating in a summer camp which he ran.
The defendant played a "treat game" with the minors, the legal counsel said, in which he would go into the children's bedrooms when they were preparing to sleep and tell them to ingest treats "rapidly".
She stated to the judge the man had played this game with the boys "over an extended period", and youngsters had earlier experienced illness the subsequent day.
She explained the man had been able to explain this repeatedly as the children being "overexcited from fun", until his stepchild had suspicions in recently.
The prosecutor continued: "In the summer" his family member had suspicions about the situation, for good reason.
"They chose" to examine in the defendant's belongings."
The legal counsel stated items including baby oil, petroleum jelly and injection devices were located, and his stepson notified the authorities about his suspicions.
She explained the man proceeded to engage in the "treat game" with six boys that evening - that Saturday - and they were everyone unwell the subsequent day.
"The police had not responded by that point," she added.
The police watchdog, the police conduct office, previously told that it was examining law enforcement's management of the situation.
Mrs Prior said the children were struggling to walk due to their condition, so the family member notified the law enforcement again.
She stated Ruben then conducted the "sweet game" in a space of five youngsters.
