An individual who contaminated sweets with tranquilliser and gave them to minors at a youth camp in the area has admitted sexual offences against two young males aged nine and 10.
The defendant was taken into custody after eight children and one adult became sick at Stathern Lodge in the summer month.
The 76-year-old, from the Nottinghamshire area, confessed to a total of 17 charges when he stood at Leicester Crown Court on Friday.
Yet, he disputed one particular crime he was charged with, which was concerning a nine-year-old child.
Ruben was kept in jail prior to a further hearing on November 28th.
'Treat game'
The prosecutor, presenting evidence, outlined the criminal behavior to the court.
She stated his those affected were disadvantaged youngsters who were participating in a summer program which he managed.
Ruben conducted a "candy game" with the children, the prosecutor stated, in which he would enter the children's bedrooms when they were preparing to sleep and request they to consume candy "as fast as possible".
She informed the proceedings the man had played this game with the boys "for many years", and youngsters had previously become sick the next day.
She stated the defendant had been capable of justifying this repeatedly as the children being "overexcited from fun", until his family member had worries in July 2025.
Mrs Prior KC added: "This year his family member had suspicions about the activities, justifiably.
"They decided to examine in the man's possessions."
The legal counsel said objects including baby oil, ointment and medical needles were discovered, and his stepchild contacted the police about his worries.
She stated Ruben went on to engage in the "treat game" with six youngsters that evening - Saturday 26 July - and they were all ill the following morning.
"Law enforcement" had not arrived by that time," she stated further.
The police watchdog, the Independent Office for Police Conduct, had stated that it was examining Leicestershire Police's handling of the events.
The prosecutor explained the youngsters were unable to walk properly due to their sickness, so Ruben's stepson contacted the police again.
She explained the man then conducted the "candy game" in a area of five youngsters.
