A person who laced treats with sleeping medication and gave them to youngsters at a youth camp in the area has pleaded guilty to sexual crimes against two boys aged nine and 10.
The defendant was taken into custody after eight minors and an older person became sick at the location in the summer month.
The 76-year-old, from Ruddington in Nottinghamshire, confessed to a total of 17 charges when he stood at Leicester Crown Court on Friday.
Yet, he denied one of the sexual offences he was accused of, which was involving a nine-year-old boy.
The defendant was remanded in custody prior to a further hearing on late November.
'Candy game'
The legal representative, prosecuting, described Ruben's offending to the legal proceedings.
She said his targets were children from difficult backgrounds who were attending a summer program which he managed.
Ruben conducted a "candy game" with the youngsters, the prosecutor stated, in which he would access the sleeping quarters when they were settling down and request they to eat sweets "as quickly as they can".
She informed the proceedings the man had played this game with the young males "over an extended period", and youngsters had previously become sick the next day.
She explained the defendant had been able to explain this over a long period as the youngsters being "overstimulated by activities", until his family member had concerns in recently.
The prosecutor added: "This year his stepson had worries about what was going on, for good reason.
"They chose" to investigate in the man's possessions."
The prosecutor stated items including baby oil, Vaseline and medical needles were discovered, and his stepchild contacted the law enforcement about his worries.
She stated the man proceeded to play the "treat game" with six children that evening - Saturday 26 July - and they were all sick the subsequent day.
"Authorities" had not responded by that point," she continued.
The oversight body, the police conduct office, previously told that it was investigating law enforcement's management of the events.
Mrs Prior said the youngsters were unable to walk properly due to being ill, so the family member called the law enforcement again.
She stated the defendant then conducted the "candy game" in a area of five children.
