An individual who contaminated sweets with tranquilliser and provided them to minors at a summer camp in the region has admitted sexual crimes against two boys aged between nine and ten.
The defendant was detained after eight children and one adult became sick at Stathern Lodge in mid-summer.
The 76-year-old, from the Nottinghamshire area, confessed to a multiple criminal counts when he stood at the courthouse on recently.
Nevertheless, he denied one particular crime he was charged with, which was against a young boy.
The defendant was held in detention ahead of a subsequent court date on late November.
'Candy game'
Mary Prior KC, handling the case, described the criminal behavior to the court.
She stated his targets were children from difficult backgrounds who were attending a summer program which he operated.
The man conducted a "candy game" with the youngsters, the prosecutor explained, in which he would go into the children's bedrooms when they were preparing to sleep and ask them to consume candy "as fast as possible".
She told the court the man had conducted this practice with the children "over an extended period", and children had earlier experienced illness the following morning.
She said the defendant had been capable of justifying this over a long period as the children being "overwrought by enjoyment", until his family member had suspicions in recently.
The prosecutor continued: "Recently" his family member had worries about what was going on, justifiably.
"They decided to examine in the man's possessions."
Mrs Prior KC said objects including infant oil, petroleum jelly and medical needles were discovered, and his family member notified the police about his concerns.
She explained Ruben proceeded to conduct the "sweet game" with six children that time - July 26th - and they were all sick the subsequent day.
"Authorities" had not arrived by that stage," she added.
The police watchdog, the police conduct office, earlier informed that it was examining the police response of the incident.
The legal representative stated the youngsters were having difficulty walking due to their condition, so the family member notified the law enforcement again.
She said Ruben then conducted the "candy game" in a space of five minors.
