A person who contaminated sweets with sleeping medication and gave them to youngsters at a youth camp in the region has admitted sexual offences against two children both nine and ten years old.
The defendant was arrested after eight minors and a grown-up became sick at the location in July.
The elderly man, from the Nottinghamshire area, confessed to a total of 17 charges when he was present at Leicester Crown Court on the end of the week.
Nevertheless, he denied one particular crime he was accused of, which was involving a nine-year-old boy.
Ruben was remanded in custody prior to a additional proceeding on late November.
Mary Prior KC, handling the case, detailed Ruben's offending to the legal proceedings.
She explained his victims were children from difficult backgrounds who were staying at a youth camp which he operated.
The man played a "treat game" with the youngsters, the prosecutor stated, in which he would go into the children's bedrooms when they were settling down and request they to ingest treats "as fast as possible".
She stated to the judge the man had conducted this practice with the boys "repeatedly", and youngsters had earlier experienced illness the next day.
She explained the defendant had been successful in rationalizing this over a long period as the children being "overexcited from fun", until his stepson had suspicions in recently.
The legal representative added: "This year his family member had concerns about the activities, with valid cause.
"They chose" to investigate in the man's possessions."
Mrs Prior KC explained objects including infant oil, Vaseline and syringes were located, and his stepchild alerted the authorities about his worries.
She explained the defendant proceeded to conduct the "candy game" with six boys that evening - July 26th - and they were everyone unwell the subsequent day.
"Authorities" had not arrived by that point," she stated further.
The oversight body, the Independent Office for Police Conduct, earlier informed that it was reviewing law enforcement's management of the incident.
The prosecutor said the youngsters were having difficulty walking due to their condition, so the stepson notified the police again.
She said the man then conducted the "treat game" in a room of five children.
