A person who contaminated sweets with sedative and gave them to children at a summer camp in the region has pleaded guilty to sexual crimes against two children who were nine and 10.
The defendant was detained after eight youngsters and a grown-up became sick at the location in the summer month.
The 76-year-old, from the Nottinghamshire area, pleaded guilty to a multiple criminal counts when he was present at Leicester Crown Court on the end of the week.
Nevertheless, he denied a single sexual charge he was charged with, which was against a nine-year-old child.
Ruben was remanded in custody prior to a additional proceeding on late November.
'Sweet game'
The prosecutor, handling the case, detailed Ruben's offending to the court.
She said his those affected were disadvantaged youngsters who were staying at a summer camp which he managed.
Ruben engaged in a "candy game" with the children, the prosecutor explained, in which he would go into the children's bedrooms when they were getting ready for bed and request they to eat sweets "as fast as possible".
She told the court Ruben had engaged in this activity with the boys "repeatedly", and youngsters had previously fallen ill the next day.
She explained Ruben had been able to explain this repeatedly as the minors being "overstimulated by activities", until his family member had worries in recently.
The prosecutor added: "Recently" his stepchild had suspicions about the situation, for good reason.
"They chose" to investigate in the man's possessions."
The prosecutor explained objects including baby oil, Vaseline and injection devices were found, and his stepson notified the law enforcement about his concerns.
She explained the defendant went on to play the "treat game" with six youngsters that time - July 26th - and they were all ill the subsequent day.
"The police had not responded by that stage," she continued.
The police watchdog, the Independent Office for Police Conduct, had stated that it was examining law enforcement's management of the incident.
The prosecutor said the minors were having difficulty walking due to their condition, so Ruben's stepson notified the authorities again.
She stated Ruben then conducted the "treat game" in a space of five children.
