A person who laced treats with sedative and gave them to children at a youth camp in Leicestershire has admitted sexual offenses against two boys who were nine and 10.
The defendant was taken into custody after eight minors and one adult experienced illness at the location in the summer month.
The senior citizen, from the Nottinghamshire area, pleaded guilty to a total of 17 charges when he stood at the courthouse on recently.
However, he refused to admit a single sexual charge he was charged with, which was involving a nine-year-old child.
Ruben was kept in jail ahead of a further hearing on late November.
'Sweet game'
The legal representative, handling the case, detailed Ruben's offending to the judicial body.
She explained his targets were disadvantaged youngsters who were participating in a summer camp which he managed.
The defendant engaged in a "treat game" with the children, the legal counsel said, in which he would go into the children's bedrooms when they were preparing to sleep and tell them to ingest treats "as quickly as they can".
She stated to the judge the defendant had played this game with the boys "for many years", and children had previously fallen ill the subsequent day.
She stated the man had been successful in rationalizing this repeatedly as the youngsters being "overexcited from fun", until his stepchild had concerns in recently.
Mrs Prior KC added: "This year his stepson had suspicions about what was going on, justifiably.
"They resolved" to have a look in the individual's items."
Mrs Prior KC stated objects including infant oil, ointment and syringes were found, and his stepson contacted the law enforcement about his worries.
She explained the defendant went on to engage in the "sweet game" with six boys that time - that Saturday - and they were all ill the following morning.
"The police had not arrived by that point," she added.
The oversight body, the police conduct office, earlier informed that it was investigating the police response of the situation.
Mrs Prior explained the youngsters were having difficulty walking due to their sickness, so the family member called the law enforcement a second time.
She said the man then played the "sweet game" in a room of five minors.
