An individual who contaminated treats with sleeping medication and gave them to youngsters at a summer camp in Leicestershire has pleaded guilty to sexual crimes against two boys both between nine and ten.
The defendant was detained after eight children and a grown-up became sick at the location in July.
The 76-year-old, from the Nottinghamshire area, confessed to a series of 17 offences when he stood at the courthouse on recently.
However, he disputed a single sexual charge he was charged with, which was involving a nine-year-old child.
Ruben was held in detention before a subsequent court date on 28 November.
'Sweet game'
Mary Prior KC, prosecuting, outlined the criminal behavior to the judicial body.
She said his those affected were under-privileged children who were staying at a summer program which he operated.
Ruben played a "sweet game" with the youngsters, the prosecutor explained, in which he would access the children's bedrooms when they were getting ready for bed and request they to consume candy "rapidly".
She informed the proceedings the man had played this game with the children "repeatedly", and children had previously fallen ill the following morning.
She said the defendant had been able to explain this over a long period as the minors being "overwrought by enjoyment", until his stepson had suspicions in recently.
The legal representative added: "This year his stepson had concerns about the activities, justifiably.
"They resolved" to have a look in the defendant's belongings."
The prosecutor said materials including baby oil, ointment and medical needles were located, and his family member notified the law enforcement about his suspicions.
She said the man proceeded to conduct the "treat game" with six children that evening - Saturday 26 July - and they were all ill the next day.
"The police had not responded by that time," she stated further.
The regulatory agency, the Independent Office for Police Conduct, had stated that it was investigating law enforcement's management of the events.
Mrs Prior stated the youngsters were having difficulty walking due to their condition, so the stepson contacted the law enforcement again.
She explained Ruben then conducted the "sweet game" in a space of five youngsters.
