An individual who contaminated sweets with tranquilliser and gave them to children at a summer camp in the area has pleaded guilty to sexual offenses against two boys both between nine and ten.
The defendant was detained after eight minors and a grown-up experienced illness at the location in July.
The 76-year-old, from that region, pleaded guilty to a total of 17 charges when he appeared at the courthouse on Friday.
Yet, he denied one particular crime he was accused of, which was against a nine-year-old child.
The defendant was held in detention ahead of a subsequent court date on late November.
'Candy game'
The legal representative, presenting evidence, described Ruben's offending to the legal proceedings.
She said his victims were under-privileged children who were attending a summer camp which he ran.
The man played a "candy game" with the minors, Mrs Prior explained, in which he would access the children's bedrooms when they were settling down and ask them to ingest treats "rapidly".
She informed the proceedings Ruben had engaged in this activity with the young males "for many years", and children had previously fallen ill the next day.
She explained the man had been capable of justifying this repeatedly as the youngsters being "overstimulated by activities", until his stepchild had concerns in recently.
The legal representative continued: "Recently" his stepchild had suspicions about the situation, with valid cause.
"They chose" to investigate in the individual's items."
The legal counsel stated items including baby oil, Vaseline and syringes were discovered, and his stepson alerted the police about his worries.
She said the defendant continued to play the "treat game" with six boys that evening - Saturday 26 July - and they were all sick the next day.
"The police had not gone out by that time," she continued.
The regulatory agency, the police conduct office, had stated that it was reviewing Leicestershire Police's handling of the situation.
The prosecutor explained the youngsters were struggling to walk due to their sickness, so the family member notified the law enforcement a second time.
She explained Ruben then engaged in the "sweet game" in a space of five children.
