A person who spiked sweets with tranquilliser and gave them to minors at a youth camp in the area has pleaded guilty to sexual crimes against two children both nine and ten years old.
The accused was arrested after eight minors and an older person became sick at Stathern Lodge in July.
The 76-year-old, from the Nottinghamshire area, admitted guilt to a total of 17 charges when he stood at Leicester Crown Court on recently.
Yet, he refused to admit one of the sexual offences he was accused of, which was concerning a young boy.
Ruben was remanded in custody before a subsequent court date on late November.
'Treat game'
The legal representative, presenting evidence, detailed the criminal behavior to the judicial body.
She explained his those affected were children from difficult backgrounds who were attending a youth camp which he operated.
The man played a "treat game" with the children, the legal counsel stated, in which he would go into the children's bedrooms when they were getting ready for bed and request they to ingest treats "as quickly as they can".
She stated to the judge Ruben had conducted this practice with the boys "for many years", and minors had previously fallen ill the subsequent day.
She explained Ruben had been able to explain this over a long period as the youngsters being "overstimulated by activities", until his stepchild had suspicions in recently.
The legal representative stated further: "In the summer" his stepson had worries about what was going on, with valid cause.
"They decided to examine in the man's possessions."
Mrs Prior KC explained objects including lubricant, ointment and syringes were found, and his stepson contacted the law enforcement about his concerns.
She stated Ruben continued to play the "treat game" with six youngsters that evening - July 26th - and they were all ill the subsequent day.
"Law enforcement" had not gone out by that stage," she added.
The police watchdog, the investigative body, had stated that it was investigating the police response of the incident.
The legal representative explained the children were having difficulty walking due to being ill, so Ruben's stepson notified the police a second time.
She said Ruben then played the "sweet game" in a space of five minors.
