A man who contaminated sweets with sleeping medication and distributed them to minors at a summer camp in the area has pleaded guilty to sexual offences against two children aged between nine and ten.
The defendant was arrested after eight youngsters and an older person became sick at the location in the summer month.
The 76-year-old, from the Nottinghamshire area, admitted guilt to a series of 17 offences when he was present at the judicial center on Friday.
Yet, he denied one of the sexual offences he was accused of, which was against a nine-year-old child.
The defendant was kept in jail prior to a further hearing on November 28th.
'Sweet game'
The legal representative, presenting evidence, described the criminal behavior to the court.
She stated his those affected were disadvantaged youngsters who were attending a youth camp which he managed.
Ruben engaged in a "candy game" with the youngsters, the legal counsel stated, in which he would enter the children's bedrooms when they were settling down and tell them to consume candy "as quickly as they can".
She informed the proceedings Ruben had engaged in this activity with the children "over an extended period", and children had earlier experienced illness the subsequent day.
She stated Ruben had been successful in rationalizing this for many years as the minors being "overwrought by enjoyment", until his stepchild had concerns in recently.
Mrs Prior KC added: "This year his stepchild had concerns about what was going on, with valid cause.
"They resolved" to examine in the individual's items."
The prosecutor stated objects including baby oil, Vaseline and injection devices were found, and his family member notified the authorities about his worries.
She said the defendant continued to conduct the "sweet game" with six youngsters that night - Saturday 26 July - and they were everyone unwell the subsequent day.
"The police had not responded by that time," she stated further.
The oversight body, the Independent Office for Police Conduct, previously told that it was examining law enforcement's management of the incident.
The prosecutor explained the children were unable to walk properly due to being ill, so the family member called the police again.
She stated Ruben then engaged in the "treat game" in a area of five minors.
