A man who contaminated sweets with tranquilliser and distributed them to minors at a summer program in the region has confessed to sexual offences against two children both between nine and ten.
The accused was arrested after eight minors and a grown-up fell ill at the facility in mid-summer.
The 76-year-old, from the Nottinghamshire area, confessed to a series of 17 offences when he was present at the judicial center on Friday.
Nevertheless, he denied a single sexual charge he was accused of, which was concerning a nine-year-old boy.
Ruben was remanded in custody ahead of a additional proceeding on 28 November.
'Sweet game'
Mary Prior KC, handling the case, detailed the criminal behavior to the court.
She stated his victims were under-privileged children who were attending a summer camp which he ran.
The man conducted a "treat game" with the children, Mrs Prior explained, in which he would go into the children's bedrooms when they were settling down and request they to consume candy "as quickly as they can".
She stated to the judge the defendant had engaged in this activity with the boys "for many years", and children had previously fallen ill the next day.
She explained the man had been able to explain this over a long period as the children being "overexcited from fun", until his stepson had suspicions in recently.
The prosecutor continued: "In the summer" his stepson had concerns about the activities, with valid cause.
"They chose" to examine in the individual's items."
The legal counsel explained materials including baby oil, Vaseline and injection devices were found, and his stepson notified the law enforcement about his worries.
She stated Ruben went on to conduct the "sweet game" with six children that time - July 26th - and they were everyone unwell the subsequent day.
"Law enforcement" had not gone out by that point," she stated further.
The oversight body, the Independent Office for Police Conduct, had stated that it was reviewing law enforcement's management of the situation.
The legal representative stated the minors were having difficulty walking due to their sickness, so the stepson notified the law enforcement again.
She explained Ruben then engaged in the "candy game" in a area of five youngsters.
