An individual who contaminated treats with sleeping medication and gave them to minors at a summer camp in the area has confessed to sexual crimes against two boys aged nine and 10.
The accused was arrested after eight minors and an older person fell ill at the location in mid-summer.
The elderly man, from the Nottinghamshire area, pleaded guilty to a total of 17 charges when he was present at Leicester Crown Court on recently.
However, he denied one of the sexual offences he was facing, which was concerning a nine-year-old boy.
The defendant was remanded in custody before a further hearing on 28 November.
'Treat game'
The prosecutor, presenting evidence, outlined Ruben's offending to the legal proceedings.
She stated his targets were under-privileged children who were staying at a youth camp which he managed.
The defendant conducted a "sweet game" with the children, the prosecutor stated, in which he would go into the sleeping quarters when they were preparing to sleep and tell them to eat sweets "as fast as possible".
She stated to the judge the man had played this game with the boys "repeatedly", and youngsters had previously fallen ill the next day.
She explained the man had been capable of justifying this repeatedly as the youngsters being "overwrought by enjoyment", until his stepchild had suspicions in recently.
The legal representative continued: "In the summer" his stepchild had suspicions about what was going on, justifiably.
"They resolved" to have a look in the defendant's belongings."
The legal counsel stated materials including lubricant, ointment and syringes were found, and his stepson alerted the law enforcement about his worries.
She said Ruben continued to conduct the "sweet game" with six boys that time - July 26th - and they were all sick the subsequent day.
"Authorities" had not arrived by that time," she added.
The regulatory agency, the Independent Office for Police Conduct, previously told that it was examining law enforcement's management of the events.
The prosecutor said the children were unable to walk properly due to their sickness, so the stepson contacted the police once more.
She stated the man then conducted the "candy game" in a area of five minors.
