A person who spiked treats with sleeping medication and provided them to minors at a youth camp in the region has admitted sexual offences against two boys who were nine and 10.
The defendant was taken into custody after eight children and a grown-up fell ill at the location in the summer month.
The elderly man, from the Nottinghamshire area, admitted guilt to a total of 17 charges when he stood at the judicial center on the end of the week.
Nevertheless, he disputed one particular crime he was facing, which was involving a young boy.
Ruben was kept in jail before a further hearing on late November.
'Sweet game'
The legal representative, prosecuting, outlined the criminal behavior to the legal proceedings.
She stated his victims were disadvantaged youngsters who were attending a youth camp which he ran.
Ruben played a "sweet game" with the minors, Mrs Prior said, in which he would access the children's bedrooms when they were getting ready for bed and request they to eat sweets "as quickly as they can".
She informed the proceedings the defendant had played this game with the children "for many years", and youngsters had previously fallen ill the subsequent day.
She said the man had been capable of justifying this over a long period as the youngsters being "overwrought by enjoyment", until his stepchild had suspicions in recently.
The prosecutor continued: "This year his stepson had suspicions about what was going on, with valid cause.
"They decided to have a look in the man's possessions."
Mrs Prior KC stated objects including lubricant, Vaseline and injection devices were located, and his family member alerted the police about his suspicions.
She stated the defendant went on to conduct the "candy game" with six youngsters that evening - that Saturday - and they were everyone unwell the following morning.
"Authorities" had not gone out by that point," she stated further.
The oversight body, the Independent Office for Police Conduct, earlier informed that it was reviewing Leicestershire Police's handling of the situation.
The legal representative explained the youngsters were struggling to walk due to their condition, so Ruben's stepson contacted the law enforcement once more.
She explained the man then engaged in the "candy game" in a room of five children.
