An individual who laced treats with tranquilliser and gave them to youngsters at a youth camp in the region has pleaded guilty to sexual crimes against two boys aged nine and ten years old.
The accused was detained after eight children and one adult became sick at the location in the summer month.
The 76-year-old, from that region, admitted guilt to a total of 17 charges when he was present at Leicester Crown Court on recently.
However, he denied a single sexual charge he was charged with, which was involving a nine-year-old boy.
The defendant was kept in jail ahead of a further hearing on November 28th.
'Sweet game'
The legal representative, presenting evidence, described the defendant's actions to the legal proceedings.
She stated his targets were under-privileged children who were participating in a summer camp which he ran.
The defendant played a "treat game" with the minors, the legal counsel said, in which he would go into the boys' rooms when they were getting ready for bed and request they to ingest treats "rapidly".
She informed the proceedings Ruben had engaged in this activity with the children "repeatedly", and children had earlier experienced illness the following morning.
She said the defendant had been successful in rationalizing this for many years as the children being "overexcited from fun", until his family member had worries in recently.
The legal representative continued: "This year his stepson had suspicions about what was going on, for good reason.
"They chose" to have a look in the man's possessions."
The legal counsel said items including infant oil, petroleum jelly and medical needles were discovered, and his family member notified the police about his worries.
She said Ruben proceeded to play the "sweet game" with six youngsters that time - that Saturday - and they were all ill the following morning.
"The police had not gone out by that time," she continued.
The oversight body, the police conduct office, earlier informed that it was examining Leicestershire Police's handling of the events.
Mrs Prior explained the children were unable to walk properly due to their condition, so the family member contacted the authorities a second time.
She explained Ruben then conducted the "sweet game" in a area of five minors.
