An individual who spiked treats with tranquilliser and distributed them to minors at a youth camp in the region has admitted sexual offenses against two boys aged nine and 10.
The defendant was detained after eight minors and an older person experienced illness at the facility in the summer month.
The 76-year-old, from the Nottinghamshire area, pleaded guilty to a series of 17 offences when he stood at the courthouse on Friday.
Nevertheless, he refused to admit a single sexual charge he was accused of, which was concerning a young boy.
Ruben was held in detention before a additional proceeding on late November.
'Treat game'
Mary Prior KC, handling the case, described the criminal behavior to the judicial body.
She said his targets were children from difficult backgrounds who were staying at a youth camp which he operated.
Ruben played a "sweet game" with the minors, Mrs Prior explained, in which he would enter the boys' rooms when they were getting ready for bed and tell them to ingest treats "as fast as possible".
She informed the proceedings the man had conducted this practice with the young males "repeatedly", and youngsters had previously become sick the next day.
She stated the man had been capable of justifying this repeatedly as the children being "overwrought by enjoyment", until his stepson had concerns in recently.
The legal representative added: "This year his stepson had worries about the activities, for good reason.
"They resolved" to examine in the individual's items."
Mrs Prior KC explained objects including lubricant, ointment and medical needles were found, and his stepson contacted the law enforcement about his suspicions.
She said Ruben went on to engage in the "treat game" with six boys that night - that Saturday - and they were everyone unwell the following morning.
"Authorities" had not gone out by that stage," she stated further.
The police watchdog, the police conduct office, earlier informed that it was investigating the police response of the incident.
Mrs Prior explained the youngsters were unable to walk properly due to being ill, so the stepson notified the law enforcement once more.
She explained Ruben then engaged in the "sweet game" in a space of five youngsters.
