A person who spiked treats with tranquilliser and gave them to children at a summer camp in the area has confessed to sexual offences against two children both nine and ten years old.
The defendant was taken into custody after eight children and an older person became sick at the facility in the summer month.
The elderly man, from the Nottinghamshire area, confessed to a total of 17 charges when he stood at the courthouse on the end of the week.
Yet, he denied a single sexual charge he was charged with, which was involving a young boy.
Ruben was kept in jail prior to a additional proceeding on late November.
'Candy game'
The prosecutor, prosecuting, detailed Ruben's offending to the legal proceedings.
She explained his those affected were under-privileged children who were staying at a youth camp which he operated.
Ruben conducted a "sweet game" with the minors, the legal counsel explained, in which he would access the sleeping quarters when they were getting ready for bed and tell them to eat sweets "as quickly as they can".
She told the court the defendant had played this game with the young males "repeatedly", and children had previously become sick the following morning.
She said Ruben had been capable of justifying this repeatedly as the youngsters being "overstimulated by activities", until his stepson had suspicions in recently.
The legal representative stated further: "In the summer" his family member had suspicions about the situation, for good reason.
"They resolved" to investigate in the defendant's belongings."
Mrs Prior KC said materials including baby oil, ointment and syringes were located, and his stepson notified the law enforcement about his worries.
She said the defendant continued to play the "treat game" with six boys that evening - that Saturday - and they were all sick the next day.
"The police had not gone out by that point," she stated further.
The police watchdog, the Independent Office for Police Conduct, had stated that it was examining Leicestershire Police's handling of the incident.
Mrs Prior explained the children were unable to walk properly due to being ill, so the family member contacted the law enforcement once more.
She said the defendant then played the "treat game" in a space of five children.
