A person who contaminated treats with tranquilliser and distributed them to youngsters at a summer program in the area has confessed to sexual offences against two children who were nine and ten years old.
Jon Ruben was detained after eight minors and an older person experienced illness at Stathern Lodge in July.
The 76-year-old, from Ruddington in Nottinghamshire, pleaded guilty to a total of 17 charges when he appeared at Leicester Crown Court on Friday.
Yet, he refused to admit one of the sexual offences he was facing, which was involving a nine-year-old boy.
The defendant was kept in jail prior to a subsequent court date on late November.
'Sweet game'
The legal representative, handling the case, described the defendant's actions to the court.
She explained his those affected were disadvantaged youngsters who were staying at a youth camp which he ran.
The man conducted a "candy game" with the minors, Mrs Prior explained, in which he would go into the sleeping quarters when they were preparing to sleep and request they to eat sweets "rapidly".
She told the court Ruben had engaged in this activity with the young males "repeatedly", and minors had earlier experienced illness the following morning.
She explained the defendant had been capable of justifying this over a long period as the youngsters being "overwrought by enjoyment", until his stepson had worries in recently.
The legal representative stated further: "This year his stepchild had suspicions about what was going on, for good reason.
"They resolved" to investigate in the individual's items."
The legal counsel stated materials including baby oil, petroleum jelly and medical needles were discovered, and his stepchild alerted the law enforcement about his suspicions.
She stated Ruben went on to conduct the "sweet game" with six boys that time - July 26th - and they were everyone unwell the next day.
"Law enforcement" had not arrived by that stage," she stated further.
The oversight body, the police conduct office, had stated that it was investigating Leicestershire Police's handling of the events.
The legal representative explained the youngsters were unable to walk properly due to being ill, so Ruben's stepson called the authorities a second time.
She explained the man then conducted the "candy game" in a area of five children.
