An individual who laced sweets with tranquilliser and provided them to children at a youth camp in the region has admitted sexual crimes against two boys aged between nine and ten.
The defendant was detained after eight youngsters and one adult became sick at the location in July.
The elderly man, from that region, confessed to a multiple criminal counts when he stood at the courthouse on recently.
Nevertheless, he refused to admit a single sexual charge he was charged with, which was involving a nine-year-old boy.
Ruben was kept in jail before a further hearing on 28 November.
'Treat game'
The prosecutor, prosecuting, described Ruben's offending to the judicial body.
She said his targets were children from difficult backgrounds who were attending a summer program which he ran.
Ruben conducted a "sweet game" with the children, the prosecutor said, in which he would access the boys' rooms when they were getting ready for bed and tell them to consume candy "as fast as possible".
She informed the proceedings Ruben had conducted this practice with the boys "repeatedly", and youngsters had previously become sick the next day.
She said Ruben had been capable of justifying this over a long period as the youngsters being "overstimulated by activities", until his stepchild had concerns in recently.
The legal representative continued: "This year his family member had suspicions about the situation, with valid cause.
"They chose" to have a look in the man's possessions."
The legal counsel explained materials including lubricant, petroleum jelly and injection devices were found, and his stepson notified the authorities about his concerns.
She said Ruben went on to engage in the "sweet game" with six boys that time - July 26th - and they were all sick the next day.
"The police had not responded by that stage," she added.
The regulatory agency, the police conduct office, previously told that it was reviewing Leicestershire Police's handling of the events.
Mrs Prior stated the children were having difficulty walking due to being ill, so Ruben's stepson contacted the authorities again.
She explained the defendant then conducted the "sweet game" in a room of five minors.
